Tom Koracick

Tom Koracick is an attending neurosurgeon at Grey Sloan Memorial Hospital. He was Head of Neurosurgery at Johns Hopkins Hospital, where he trained Amelia Shepherd in the field. In Seattle, he developed a relationship with Teddy Altman until she chose Owen after having his baby, though the two later developed a short-lived affair.

Early Life
At some point in his life, Tom got married and had a son named David with his wife. When David was 10 years old, he died when he got hit in the head with a baseball bat. David's death happened two weeks before Halloween, which was David's favorite holiday and Tom and David's thing. They had prepared a Luke Skywalker costume to go trick-or-treating that year. David never got a chance to wear it and the costume hung on the his bedroom door for months as Tom couldn't bring himself to take it down. His son's death left him hating Halloween.

Amelia's Tumor
After learning she had a large brain tumor, Amelia called Tom, her former mentor, to come to Seattle to operate on her. After he arrived, he agreed to operate and also made it clear that Amelia wouldn't be allowed to treat patients until he cleared her, as the tumor was affecting her judgment.

Amelia's surgery went smoothly and a few days afterward, Koracick cleared Amelia to go home.

Harmony Vasquez
When Amelia attempted surgery on her first day back, she asked Tom to scrub in, unsure she could handle it herself. He scrubbed in, but she was able to remove the tumor easily without his help. After the surgery, he admitted he'd hoped she'd fail because that would mean she's not better than him anymore. After their shared success, they had sex in an on-call room.

Kimmie Park
Amelia called Koracick back to Seattle again to help with researching a technique to remove Kimmie's tumor. After seeing Kimmie and her scans, Koracick believed it was pointless to try to perfect it within such a deadline and wanted to quit, but during a fight with Amelia over the issue, he had an epiphany and discussed a possible solution with Amelia. They later tested it and while it didn't work perfectly, it had more success than their prior attempts, giving them hope.

Game Night
Tom came to the game night Maggie organized so Amelia and Meredith could meet Clive. He played as April's partner and had a good time. When the night abruptly ended, Tom ended up driving an intoxicated April home.

Helping April
After waking up from their one-night stand, Tom stuck around at her place and tried to figure out why she was so different from the woman Amelia had chosen for her Power of Attorney during her surgery. He eventually figured out that it was a crisis of faith and talked to her about his own faith, which was tested when his son died in a freak accident involving a baseball bat to the head at age ten. His marriage fell apart after the death of their son and his priest recommended talking to God. Since he didn't want to talk to God, he decided to go to Mass and speak to his son instead, something he told April he still does.

Treating Noah and New Direction with Kimmie
After Noah Brosniak was diagnosed with an HH tumor, Tom and Amelia decided to use the treatment they were developing for Kimmie to help him. They had to control the lasers very carefully to make sure they were destroying the tumor but not his brain. The procedure was successful and Noah lived, but the difficulty made them realize it would take more time than Kimmie had left to fine-tune it to work for her type of tumor. Therefore, they decided to develop a treatment plan that would allow Kimmie to live until summer when Koracick planned to take vacation time and fly Peg and Kimmie to New York to see as many Broadway shows as possible before she died. Alex became angry when he learned of this plan and shoved Tom up against a cabinet before backing off.

Continuing Research
Tom and Amelia continued their research into using the laser treatments to remove tumors.

Tad
Tom stepped in to help when he saw Vik freaking out over Tad, a patient in the ER with a nosebleed. By the time they got to him, it was too late and Tad died.

Catherine's Cancer
Tom and Meredith were both summoned to Los Angeles for a VIP patient. They speculated that it was someone famous. When they arrived, Catherine told them it was a 65-year-old female who had severe back pain. She showed them the patient's scans, which showed a large spinal tumor. Then she revealed that she was the patient. Tom ordered a biopsy so they would know if the tumor was benign or malignant. When the tumor was found to be malignant, Tom became worried for his friend. She told him of all the things she'd been through and challenged him to find a way for her to live through this as well.

Tom worked with Amelia to create a surgical plan to remove Catherine's tumor, which they knew would be extremely difficult. Jo helped them out by showing them a new thing she had read about to visualize the tumor in 3D.

Tom and Amelia took her in for her surgery. They worked for hours on her spine from the back, but when they couldn't free the tumor, they decided to move her onto her side and come at it from the front and the back at the same time. They discovered that the tumor was attached to her brachial plexus. They used Richard's cancer pen to find the edges of the cancer, but despite this, they had to leave a piece of the tumor behind, meaning she'd be living with cancer and would need frequent scans to track the tumor.

Lucille Reid
Tom was called in to consult on the case of Lucille Reid, who had an aneurysm in her brain. He and Teddy operated together to fix her. They also observed that she had two men doting over her: her husband, Marvin, and her best friend, Julian. After working on the case, Tom wondered about the analogous situation happening with her and Owen. That night, she went to his hotel room to show him that she was only ever meant to be friends with Owen.

Catherine's Party
Tom attended Catherine's party, with Teddy as his guest. At the party, he and Owen butted heads over his relationship with Teddy, which included a planned pre-baby vacation to Palm Springs. Owen confronted him about it, but he was unconcerned until Owen said that he's not a father. When he heard that, Tom punched Owen. Teddy corrected Owen that Tom is a father and stopped Owen from punching Tom back. Tom then iced his hand as the party continued until a plastic pan accidentally placed in the oven forced an evacuation of the building.

Conflict with Owen
After Owen left a birthing class Teddy had invited Tom to be with Teddy after she experienced some troubling symptoms, Tom realized Owen was trying to shut him out of the experience. He warned Owen that he would fight for Teddy to have the person who loves her and only her.

Teddy's House Hunt
When Teddy decided she wanted to buy a house before the baby was born, Tom helped her look, as he claimed superpowers relating to houses.

Kari Donnelly
After Kari Donnelly was paralyzed in an accident, Link found a study that involved directly injecting stem cells into the spines of quadriplegic patients in the hopes of regaining the use of their arms. He suggested this treatment for Kari, who agreed to try it. In surgery, Tom injected the stem cells.

Thirteen days after her infusion, Kari still had no mobility in her upper limbs. She had other health issues associated with her paralysis, which weakened her.

Preparing for Teddy's Baby
With only three weeks left until she was due, Teddy had not purchased a house for them to live in. Tom took up the mantle and found Teddy a house that fulfilled all the requirements she'd set out. He then surprised her with a set of keys, which he admitted were just a prop because he hadn't been able to go pick up the actual house keys.

Tom later purchased a crib for Teddy's baby and said he'd put it together for her.

When Teddy went into labor, Tom remained unaware and continued to assemble the baby furniture at her new house. While working, he Skyped in to see Kari Donnelly move her fingers.

Promotion
He tried calling Teddy, but she didn't answer. He then figured she had given birth and went to the hospital. He found her in a room with her newborn daughter and a crying Leo Hunt. He admired the baby for a moment and took Leo off her hands. He knew Teddy had gotten back together with Owen after he rode in on a white horse and made all the right promises. Teddy took all the blame for her decision and told Tom he was wonderful. Tom knew that and stated it wouldn't last and that she'd come to regret her decision. He told her he would be there for her when it ended because he loved her, and in the meantime, they would remain friends. He then brought Leo back to daycare so she could rest. A week later, Tom had a meeting with Catherine and accepted her offer to become Chief Medical Officer of her Foundation, meaning he would get to oversee all Chiefs of Surgery of her Foundation's medical centers.

Tom arranged to permanently move to Seattle and he asked his protégé resident Blake Simms to move with him. Blake refused as he couldn't leave his grandmother behind. However, Tom wanted him so badly that he paid for Blake's grandmother to move to Seattle with them.

On his first day at the job, Tom enjoyed taunting Owen before revealing his promotion to him to put him in an awkward position. He made Owen let him step off the elevator first. While rounding the hospital, he found out Bailey had set up a skills lab for the residents and dismissed teaching, ignoring Jackson's remark that Grey Sloan was a teaching hospital. In the ER, he found that Owen and Maggie were working excessively to resuscitate Reid Kim. He ordered them to stop but Owen ignored him. Before he could shock Reid's heart again, the rhythm returned suddenly. Owen punted to put the already-charged paddles aside but accidentally shocked Tom in the crotch. Tom fell the floor while squirming in pain. His protégé resident Blake Simms helped him to a wheelchair and got him Catherine Fox to treat him. Owen briefly apologized while rushing the patient to the OR but he dropped by Tom's room for a proper apology afterwards. However, in the meanwhile, Tom had obtained an emergency restraining order against him for acute emotional and physical distress. Owen was baffled. Tom directed him to his lawyer for any questions and made him leave. Tom had fun in abusing the restraining order to exert power over Owen by making him leave his trauma room while he examined Owen's patient. Later, he made Owen leave the ER altogether.

After Meredith released an exposé that trashed Grey Sloan's reputation, Tom quickly came up with a plan to get the hospital free positive publicity. He called Dana and Peter Martin to inform them that Jackson Avery would operate on their daughter's deformed skull pro bono if they allowed them to film the surgery and use it for promotion. The parents consented since the surgery would otherwise require them to take out a second mortgage. Tom hired a camera crew to document Jackson's miraculous work. Jackson hated the set-up, which only increased as Tom was more concerned with getting proper testimonies as publicity material than putting the parents' concerns at ease. After Tom asked the father to repeat his testimony while filmed from another angle with less backlight, Jackson cut in and told him that the surgery was hard enough on the parents already. Tom reminded him that he was the boss and wondered if he should get Catherine to explain it to him again. However, Jackson went behind his back to have the surgery take place without being documented and had him replaced by Amelia. Tom found out and went to confront him in the OR, where Jackson told him he would call security if the camera crew came near the OR. Tom wanted to pull rank again but Jackson pointed out that he was Foundation, too, owning more shares of the hospital than anyone else, and that his cosmetic procedures provided quite an income for the hospital, so Tom better leave him alone. Tom tried to reason that fires like the one Meredith had started spread rapidly and that it would burn down more than this hospital alone but Jackson didn't budge. Tom realized that they needed good doctors to stay and went to inform Owen that he had gotten rid of the restraining order, but he came too late, as Owen had taken a job at Pac-North. Tom thought he would come to regret that and invited him to call him when that happened. He also reminded Teddy she could still call him if she regretted her choice of picking Owen over him.

Tom put Andrew on his service to get him to make Meredith make things right with the hospital. Meredith herself then turned up with a sick Zola. They did some scans and found that her shunt needed to be revised. Tom flawlessly performed the surgery.

On Halloween, Tom worked on a patient with Teddy and Bailey. While he dismissed Halloween every chance he got, Teddy was stressing out over Owen's apparent hint for her to make costumes for their children. She said they skipped so many steps from friends to a family of four that she didn't feel prepared for the situation, leaving her to feel like she had no idea what she was doing. Tom then said he didn't understand her either and told her not to let Owen make her feel inept as a mother for not making costumes like his mother had done. He finished up his part of the surgery and went back to the ER to save more Halloween casualties. The patient made it through the surgery. Afterwards, Bailey confronted Tom with his incessant complaining about the holiday and he told her that his son's death ruined Halloween for him as it used to be their thing. Hearing the story made a hormonal Bailey sob in front of him, which she had been trying to avoid, and he comforted her.

Tom stayed at the hospital while most of the attendings took the day off to support Meredith on the day of her hearing before the medical commission. He was surprised to find Amelia, Link, and Teddy back soon and learned that they had diagnosed Paul Castello, the man who had killed Derek, with a hypertensive intracerebral hemorrhage. Tom performed a craniotomy and managed to evacuate the hematoma against all odds. However, a sudden rebleed happened and Tom was unable to save Paul.

Affair with Teddy
When Tom learned that Teddy was scrubbing in with Maggie on a cardiothoracic surgery after months, he came into the gallery to observe her and complimented her technique. After the patient's heart wouldn't restart, Maggie quit because she had lost faith in her abilities. Tom tried to convince her otherwise but she had made up her mind. Tom then asked Teddy to become his Head of Cardiothoracic Surgery again. She got mad thinking he fired Maggie to give Teddy what she wanted. She told him that she loved Owen and had moved on from Tom. She said he would make some woman or several women very happy but she asked him to stop barking up this particular tree. Tom then said Maggie actually quit and he wanted her to replace her. Tom then pointed out that Owen had a baby with her and hadn't even proposed yet while Tom was ready to marry her today, which made him wonder if she really wanted to close the door on him.

Tom sprung into action when his protégé Blake Simms sustained a mid-facial fracture when a car crashed into Joe's bar. He insisted on checking the scans for brain bleeds himself and found none. He then checked if Jackson was good to operate after the long night he'd had. Jackson said he didn't need a babysitter and went ahead with the surgery. Tom requested an update on every step. Jackson couldn't help but make a snide remark about using this case to exploit Blake's vulnerability for free publicity. They neglected to provide him with updates so Tom came in furious when they were wrapping up the surgery. Owen then stopped Jackson as he saw a sign of a CSF leak. Tom scrubbed in and found and patched up the leak. Tom called Blake's grandmother and while Jackson showed her to her grandson, Tom thanked Owen for catching the CSF leak and they shook hands. At the end of the day, Tom watched in disdain as Teddy and Owen announced their engagement to the hospital staff.

Bailey took some unexpected personal time off while the injured residents were still out, increasing Tom's workload. On her first day back, he commented on her unexpected leave multiple times. At the end of the day, she told it wasn't just a vacation but instead time to grieve her miscarriage. He sympathized with her, having been through two miscarriages with Dana before they had David. He shared that it is not as easy to get over as people make it seem, as a miscarriage takes away a piece of your heart that can never be replaced. That is why he developed a habit of lighting a candle on the babies' would-be birthdays. Bailey took his advice and found comfort lighting a candle in the chapel.

Maggie met with Tom to ask her for her job back but he was hesitant as he had Teddy already to replace her. As Catherine purchased and subsequently closed down Pac-North, she had Tom interview the staff to see who could be transferred to Grey Sloan. Bailey wanted to make some recommendations but Tom refused to hear her out. Tom went to the waiting room and started with Richard. Tom immediately told him that Catherine had already secured his position at Grey Sloan, which angered Richard and made him refuse. He also met with Maggie despite Catherine already having re-hired her, too, just to make sure it wouldn't seem like he was playing favorites. However, he stressed that it was still Teddy's department. Owen grew impatient when Tom started interviewing residents after meeting all the other attendings. When Owen suggested he was playing a game, Tom promised him he would be out in time for his wedding and continued to interview the residents. When he had seen everyone but Owen, Tom took his time consulting with Catherine on the phone. At the end of the day, he found Bailey, Jackson, Richard, Meredith, and Owen waiting for him in the conference room. They told him they were prepared to quit unless he agreed to all of their terms, which he could present to Catherine as his own ideas to save face and ensure that Catherine wouldn't fire him for causing her top doctors to quit. He was forced agree to re-hire Owen and to have the Cardio and Peds departments led by Co-heads.

As a blizzard hit Seattle, Teddy learned that Amelia was on leave and asked Tom about it, but he didn't know why, only that it was not about her baby. Later, Tom brought Teddy hot cocoa as she was enjoying the snow out in the ambulance bay. She told him that she was trying to quiet her mind as she had been having this fear for months that Owen was the father of Amelia's baby. She admitted she was afraid that Owen would always be in love with Amelia. Tom assured Teddy that Owen was very much in love with her, even though he would like for it to be different. Teddy told him he was a good man. He opened up and said people didn't seem to like him despite his attempts to get in with people. Teddy told him she didn't dislike him at all. Tom then initiated a snowball fight. That night, Teddy came by his hotel room. As soon as he opened the door, she started kissing him. He let her in and closed the door.

On his way to VIP patient Griffin Ford, a multimillionaire who was behind a rocket explosion over the city causing severe injuries, Tom overheard Owen and Teddy discussing wedding venues. Tom was surprisingly nice to Owen. Teddy was afraid it would make Owen suspicious. Tom wanted to keep seeing her and discuss what it meant but Teddy said it meant nothing and that she had acted impulsively because she was afraid that Owen could be the father to Amelia's baby. Tom then went to see Griffin, who talked about the bad press the explosion had left him with. He pleaded with Tom to do a thorough examination in order to find a medical reason that could have caused him to make the mistake that led to the crash. Tom recruited Meredith, who was annoyed that Tom had cleared an entire floor for Griffin, causing troubles with admissions in the hospital. She started her exam but left it to Jackson so she could care for her own patient. Jackson couldn't find anything. Griffin then offered Tom a bribe, asking for a fake diagnosis in exchange for a large sum of money that would allow him to do good in the world. Tom consulted with Meredith about what she would do with Griffin's money and how she decided which rules to break. She gave him some ideas and said she just followed her gut in order to improve the world. Tom then decided to accept Griffin's bribe and "diagnosed" him with an aneurysm that could have influenced his judgment. At the end of the day, Teddy came to see Tom in his office and apologized to him, saying he deserved better than what she had done. She explained Tom made her feel good and like she was in control. She didn't want to hurt him because he was such a good guy. They then kissed again.

Meredith organized a pro bono surgery day with 25 surgeries scheduled. Tom increased the pressure by only allowing OR access until 7 PM. During the day, Teddy pulled him into a supply closet and told him that Owen was not the father to Amelia's baby. However, that didn't change the way that Teddy felt about Tom. She was paged away and Tom went to check on the pro bono surgeries. He found several patients and their loved ones yelling at Meredith for increased waiting times. Tom then agreed to give her more time and pay for the overtime as well. He confessed Griffin Ford gave him some money and Meredith immediately figured out what he had done. He reminded her that she told him to follow his gut to fix the world. Afterward, Tom met up with Teddy in the OR gallery and told her that while he had slept with a lot of women, he drew the line at married women because he had been the guy whose wife had slept with another man. He wanted to make it easy for Teddy so he told her to go home to Owen and spend time with him.

Tom was part of the team of physicians trying to find out what was happening to Richard. Teddy caught up with him at work and he casually suggested she not marry Owen. He then suddenly froze as they were approached by Dana Hamilton and her son, Guthrie Hamilton, who bore an uncanny resemblance to Tom and Dana's son David. Dana explained that Guthrie had a brain tumor with a spinal met and she didn't know who else to go to. Tom had Guthrie admitted and ordered new scans. Noticing how it made Tom upset, Teddy paged Amelia and informed her about the situation so she could take the case. As Amelia went to introduce herself, Tom used his busy schedule as an excuse. Owen paged Tom for a consult on Vera Kitano, who kept on singing after waking up from her surgery. Tom diagnosed musicophilia and went to check out her scans. Teddy found him in the scan room and an emotional Tom told her that he always thought he could have saved David if he had gotten him to the hospital in time, but now it was like David was there and he couldn't even stand to be in the same room as him, meaning that thought he had been holding onto was a lie. Shortly after beginning the operation, Amelia started to experience contractions. She had Tom paged to take over. He desperately asked her to work through it but she was confident he could do it. Teddy calmed him from the gallery, making him focused enough to diagnose an air embolism. They got it out and Tom finished the surgery successfully. He delivered the happy news to Dana, who apologized for having put him through this. Teddy came by his office to comfort him and apologized for the pain she had caused him. He told her she had taken away more pain than she had caused him. They briefly held hands until she pulled away and left.

Tom and Amelia agreed that Richard was suffering from Alzheimer's, which convinced Catherine to take him home. Later, Owen came to yell at Tom for ignoring his request for time off for the wedding. Tom said he had ignored the e-mail because he didn't think it was urgent based on the subject line, though Owen informed him that they had moved up the wedding to tonight. Tom was surprised but approved Owen's time off. Once he left, Tom called out Teddy for not warning him. He feigned happiness for her. When new symptoms arose, Amelia and Tom performed an EMG, which proved peripheral nerve damage, thus disqualifying the Alzheimer's diagnosis. Tom ran into Teddy again and he brought up the wedding, which he thought she was rushing to convince herself that she could live without Tom. Teddy insisted the wedding would happen, which Tom doubted. Tom then went to see Catherine, who told him she might be asking him to take on a bigger role in the Foundation as she wanted to devote more time to Richard as she was determined not to give up on him a second time. This inspired Tom to page Teddy to his office. He told her not to throw her life away and reminded her that she loved him, too. He insisted he wouldn't give up on her and said he would be waiting for her in his car at 7 PM, ready to take her wherever she wanted to go. As she started kissing him again, she said she couldn't do that but admitted she loved Tom, too. They proceeded to have sex, during which Teddy told Tom that this was goodbye as she was still going to marry Owen. Unbeknownst to them, they were recorded on a voice mail that Teddy was accidentally leaving Owen.

The affair effectively ended while word about the butt dial accident spread around the hospital.

COVID-19
When the COVID-19 pandemic hit Seattle, Bailey sprung into action to prepare the hospital for the incoming patients while Tom maintained his casual, laid-back attitude. He nonchalantly walked around the hospital with a nine-iron golf club to keep people at a distance when necessary and refused to keep Bailey informed on the order of PPE he had placed. Eventually, the delivery arrived. Tom was joined by a handful of excited doctors, amongst them Teddy, at the loading dock to unpack and distribute the box. However, they soon found that all of the boxes contained booties while there were no masks or other protective gear. Frustated by his mistake, Tom started hitting the boxes with his golf club and broke down on the spot.

Tom heard that Richard made up a system using a UV light cleaning robot to clean masks and other PPE. Afraid of facing Catherine's wrath over his mistake, he tried to convince Richard to let him take the credit for Richard's idea, which Richard refused. He hid from her throughout the day but she paged him and Richard to the conference room at the end of the day. She told Tom that the crisis had proved bigger than him and she would accept his resignation at Chief of Chiefs, in return offering him a position as neurosurgery attending. His ego bruised, Tom claimed he could find a job anywhere he wanted, though Catherine pointed out that word of his sexual escapades had gotten around. He then accepted her proposition.

Richard replaced him as Chief Medical Officer. Tom joined Owen and Jackson in the lounge as they were watching his speech announcing mandatory COVID tests for all hospital staff. He joked Richard was doing better than his last on screen performance, to which Owen reacted by throwing him out of the room. Richard helped Owen set up drive-through testing, which Tom had been putting off for weeks. Richard tasked Tom with introducing the new interns to the hospital's workings during the pandemic, but he only handed out assignments and told them to find someone else for questions. Due to his lacking guidance, James Chee failed to finish progress notes in time so Tom had to help him out. Later, while waiting in line for his COVID test, Tom overheard Owen instructing Mabel Tseng to show Sara Ortiz how to properly put on her PPE, which Owen said "someone else" should have shown her earlier. Tom took the hint. After clashing over a patient discharge with Alma Ortiz, who told him half of her class had quit, Tom went to Richard's office. Citing the disasters with the interns quitting or failing at their jobs, he told Richard he wasn't a natural teacher like him. As he prepared to go home, Teddy joined him in the lounge and asked him to let her buy him coffee to apologize for the lack of contact between them these last few months. He asked her to leave him alone so he could get over her, because she had broken him and he had had enough hurt for a lifetime. To make matters worse, Owen came in to inform Tom that his COVID test had come back positive, meaning he had to go straight home and quarantine for 14 days.

Personality
Tom puts up a tough exterior at work and he is not shy from praising his own skills, both of which contribute to other people generally disliking him. However, Tom is funny and actually an emotional person as confirmed by Lorraine Simms. As such, he knows when to let go of his tough facade and show his true colors to people who are in need of comfort, like when he helped April Kepner acknowledge her crisis of faith or when Miranda Bailey needed some comfort after suffering a miscarriage. The loss of his son David rendered him with a notable soft spot for children as evidenced by his excellent bedside manner with Kimmie Park and the lengths he went to to make her final weeks perfect for her.

Dana Hamilton
He was previously married to Dana. They had two miscarriages before their son David was born. Unfortunately, David died at the age of 10 due to a baseball accident. Tom and Dana's marriage fell apart and they divorced after their son David died. Tom mentioned to Teddy once that he knew what it was like to be cheated on, making it likely that Dana cheated on him as their marriage unraveled.

Amelia Shepherd
After Amelia's first surgery when she had recovered from her tumor, she had sex with him, where he also admitted she was a better surgeon than him.

April Kepner
He had sex with April after they met at Maggie's game night. The morning after, he helped her with her crisis of faith and shared how he dealt with his son's death.

Nicole Herman
He and Nicole had sex after she became blind.

Teddy Altman
After learning that Teddy was pregnant with Owen's baby, but they weren't a couple, Tom expressed interest. When he later found Teddy in a lounge massaging her feet, he offered her some of his fries and fed them to her because her hands were covered in feet.

After he operated on Catherine, Teddy offered to celebrate with a drink, but he took a rain check, saying he needed a shower. At Jo and Alex's New Year's Eve party, Tom and Teddy shared a kiss at midnight. Later, he saw her lying down because her feet were hurting and said she should go get a mani-pedi at his favorite place. They ended up getting mani-pedis together, which they both enjoyed.

Their relationship hit a small snag when Tom wondered about her relationship with Owen. However, she allayed his fears and he invited her into his hotel room to have dinner.

When Teddy was working on the difficult case of Elizabeth Hall, Tom was back at Hopkins. However, he came back and saw her being comforted by Owen.

Later after having a snowball fight and hot cocoa, she came to his hotel room and they kissed and he shut the door.

Familial
His son David died at the age of ten when he was hit in the head with a baseball bat. Tom always felt incredibly guilty over his death, always assuming he could have saved his son had they gotten to the hospital in time.

After operating on Catherine, he went to the chapel to talk to his son and tell him his dad did well.

Catherine Fox
He has a history with Catherine Fox. They flirted a little bit when they ran into each other again at the hospital and she invited him to return for lectures in the future.

Tom later told Meredith that Catherine was the one who woke him back up after his son died, reminding him that he was still alive and shouldn't sleepwalk through his life.

Amelia Shepherd
As her mentor, Amelia has professional respect for him, though she acknowledges and loathes his arrogance. He likes to take credit for her surgical skills. After her tumor was removed, he stayed to cover her service until she was cleared to return. However, she stopped him from leaving and asked him to join her on her first case back as she needed some hand-holding.

After they operated together, he had sex with her after he told her she was a better surgeon than him. He later claimed he only said that to get her to sleep with him, though she didn't buy that. She also told him she dislikes him intensely.

While they worked on their research together, Tom gave Amelia advice on how to get where she wanted to be with Owen.

Career
Dr. Koracick was the head neurosurgeon at Johns Hopkins Hospital. He trained Amelia Shepherd. He helped to cover her service at Grey Sloan Memorial Hospital while they planned to remove her tumor and stayed to do so until she was cleared to return to work. He later partnered with her on her innovation project regarding ultrasound ablation of inoperable gliomas and gained privileges at Grey Sloan to jump in and help out when necessary.

Catherine appointed Tom Chief Medical Officer at the Catherine Fox Foundation, meaning he was the Chief to all the Chiefs of Surgery at the Catherine Fox Medical Centers, Grey Sloan Memorial Hospital included. He then presumably quit his position at Johns Hopkins to spend his time at Grey Sloan, the best hospital of the Foundation. After he messed up a critical order of PPE during the COVID-19 pandemic, Catherine fired him and offered him an attending neurosurgeon position, which he accepted.

After that, Richard Webber, the new Chief Medical Officer, gave him his Director of the Residency Program position at Grey Sloan Memorial Hospital.
