A successful New York ER doctor soon to be married to his lovely fiance, he was dismissed from his job because he triaged a dying teenager before a billionaire hospital benefactor. The benefactor dies, after being initially stabilized following a femoral artery catheterization, from causes attributed to pericardial tamponade. Hank stands up for himself by stating he saved the kid. He spends the next month in a tailspin of broken engagements and unpaid bills before his brother convinces him to attend a posh party in the Hamptons. At the party, he saves supermodel April, and wins the favor of the German nobleman, Boris. This leads to referrals to other rich clientele. Despite Hank's dislike of the upper class, a potential love interest in local hospital administrator Jill Casey convinces him to become a concierge doctor. He drives a well-aged Saab 900 Turbo convertible. He is originally from New Jersey and sometimes throws a Jerseyism into his speech. In the episode "Keeping the Faith", he mentions that he is Jewish..
Hank Lawson's brother. He is an accountant (CPA), makes himself Hank's CFO after he establishes "HankMed" as well as the unofficial Public Relations Manager. He views the Hamptons as a place to pursue attractive women, especially Divya, who continually rebuffs him. He is materialistic, especially in comparison to Hank and when promised money and fun, he is up to do anything. He tries to promote HankMed against Hank's will, and many of his subplots revolve around him engaging in some scheme against Hank's wishes that ends up going wrong. When Hank is given a Tesla all-electric roadster by "New Parts" Newberg and her dog Koufax, Hank in turn gives it to Evan. In episode 12, "Wonderland", Evan invests all the capital from HankMed into a con stock company investment with a broker who turns out to be his and Hank's father, only to leave and inform his brother that he is going to try and get it back. He is a womanizer but it is often hinted that he is attracted to Divya, as he continues to make passes at her despite her rather harsh rebuffs. She kisses him passionately in episode 10, "Am I Blue?", to keep him from getting beaten up by the angry boyfriend of a girl Evan had been trying to be "just friends" with. By the second season finale, he has finally in a serious relationship with Paige Collins and at Hank's urging has left with her for a trip to Europe.
Hank's on-again/off-again girlfriend. She is an executive-level administrator at Hamptons Heritage, the area hospital looked down upon by the elite who have a running gag stating how it is a death trap or "taco stand", because it had saved her arm after a teenage surfing accident. Hank and Jill meet while leaving Boris's party and again when Hank is dealing with "New Parts" Newberg. At the end of the first season opener, Jill and Hank's love and career interests blossom at a clam shack. For the first three episodes Jill drives a well-aged Saab 900 Turbo convertible essentially identical to Hank's car, but replaces it with a new Toyota Prius after her Saab "dies". She describes Hank as "cute", as she says in episode 2 while she is drunk, and again at the end of the episode, when not drunk. She is often worried that her relationship with Hank will turn out like her other relationships, all of which were disasters. In episode 7 she reveals that she gave her ex-husband (Charlie) an ultimatum, either her or his job, he chose his job and left her. It is later revealed she is still legally married to Charlie, because with all his travels she could never locate him to give him the papers to sign. In the last episode of the first season, she was going to tell Hank she wanted to be with him, she sees him with another girl (his patient for the episode) and gets the wrong idea. She later kicks Charlie out of her house at the end of the first season. Her maiden name is McGillicuddy, something she is not fond of. She has three older brothers.
Hank's physician assistant. He later has her formal title changed to Physician Associate, on the grounds that people only look at the "Assistant" part of the title. She interviews to be Hank's physician assistant after word travels of Hank's instant reputation as a concierge doctor. Initially brushed off by Hank (despite her truckload of medical equipment), she has gained the job by the second episode. She is Indian and her family spends the summer in the Hamptons. Divya admits that she is practicing medicine without her parents' knowledge, stating that she is unhappy with the degree of control they try to exert over her, the most notorious example being forcing her to marry her childhood friend, an Indian man named Raj. In episode 5, "No Man Is An Island", Divya reveals to Jill that she has tried to start a concierge physician service twice before, but failed both times. She later is forced to tell her parents about her career after Evan practically told them everything (under the belief that they already knew). They accept the news, but still expect her to marry Raj and leave the Hamptons, letting her reveal that she hates the fact that her parents never consider any of her ideas. It was revealed that she first wanted to get into medicine when she was a little girl and helped take care of a cut on her friend. When she told her parents they did not listen and told her that she would get an MBA, marry Raj, and work at his business. In the last episode of the first season, she resolves to break off the engagement at the last minute. She changes her mind, and becomes engaged to Raj. In the second season, she becomes increasingly wary of her wedding, culminating in her becoming infatuated with Adam, one of HankMed's patients. In the season finale, after she and Raj are exposed to pneumonic plague, Divya decides to call off her wedding once and for all, as she felt the universe had sent her "one sign too many" that she could not ignore.
In the 2011 season premiere, Divya broke the news to her parents that she and Raj had broken off their engagement. Divya's mother tries to convince her to beg Raj to take her back. She tells her parents that she refuses to go along with their wishes and wants to marry for love instead, which upsets her father. In the episode "But There's a Catch", all signs point to the fact that Divya has been financially cut off by her parents after refusing to go through with the marriage, as her credit (which was still in her father's name) was refused when buying supplies for HankMed, her car was repossessed, and Evan finds out that she has not cashed any of the checks paid to her through the practice. Hank and Evan allow Divya to stay with them until she gets back on her feet, even going so far as to buy her a car. Divya eventually moves into a place of her own, only to discover that Raj's parents expect her personally to pay off the expenses they put into the engagement and wedding. Rather than sell her shares of HankMed, as they had intended, Divya takes a part-time shift at Hamptons Heritage to pay off the debt, but the mounting demands on her time juggling both jobs may have serious consequences.
A mysterious German nobleman with a large estate in the Hamptons (filmed at Long Island's Oheka Castle). In the series' pilot, Hank saves the life of April, a guest at Boris's party and Boris rewards Hank with a bar of solid gold, a job as concierge doctor, and use of his guest house. He has apparently referred several of Hank's patients to him and admits to "having plans" for Hank. Boris is extremely secretive, having moved to the Hamptons specifically to stay out of the public eye. Boris sometimes uses his money to bend and break rules. He owns a shark which was being used in a medical experiment and injures one of the scientists in one episode. Hank states after a physical examination that Boris is in almost perfect physical health, yet Hank knows that something is wrong. It is later discovered that Boris has a genetic disease that has affected, at least, the past three generations of his family. The condition causes a lack of muscle control, degenerating brain function, and death around the age of 44. Boris is somewhat cavalier about experimentation to cure his disease; this has led to unintended side effects such as muscle spasms and temporary blindness from not heeding Hank's advice.
In season two, Boris agrees to let Hank "quarterback" a cooperative effort between all of Boris's former doctors and researchers. Hank's first point of contact is for Dr. Marisa Casseras in Cuba, which is fortunate for Boris as they were former lovers. In "Medusa" they fly to Cuba to consult her; having diagnosed the condition, she allows for Boris to enter a clinical trial on the condition. While Hank suggests further research to confirm its success and validity, Boris begins treatment the next day. During a code blue where Boris crashes and needs to reboot, which loses the data for the trial but keeps him alive. He later decides to stay for an extended period to reconnect to Marisa, and he announces his news that Marisa will be defecting upon his return in "Whole Lotto Love". However, by the end episode it seems that she was arrested and detained, leaving a distressed, helpless Boris.
At one point, Jill drops Boris's name in an attempt to levy her way out of dealing with the hospital board. The stratagem works, but at the cost of losing Boris as a donor, as his privacy as an anonymous donor was violated. He is seen in the half-season finale flying out in a helicopter, despite his weakness, and retrieving Marisa from custody by unknown means. Also as a precaution against Eddie, he begins an investigation into the Lawsons to determine their implicitness in Eddie's role as a confidential informant, using his aide Catherine (Rena Sofer) posing as a patient. His findings are revealed to the family, which resulted in Eddie's heart attack. When it seems certain that Eddie will be convicted and sentenced to prison, he offers to have Eddie spirited out of the country and beyond extradition, but he makes it clear to Eddie that he is doing this for Hank and Evan's benefit because he believes that the brothers will be better off without Eddie in their lives. When he learns that Marisa is pregnant with his child and that Hank knew but did not tell him, he evicts Hank and Evan from his summer house. However, realizing his rashness and accepting the strength of Hank's ethics, he asks Hank to come back in season three and HankMed moves back into the summer house.
Hank and Evan's father. He is discussed extensively in season one. During Hank's adolescence and Evan's childhood, he walked out on the family when their mother was dying. Evan has been able to reconcile himself with his father's legacy, but Hank has pointedly not. At the end of season one, Evan lends all of HankMed's capital to Eddie, which almost bankrupts HankMed and leads to a rift between Hank and Evan. He makes his first on-screen appearance in the season two opener, when he returns some of Hank and Evan's money, to which Hank responds by punching him in the face. By the next episode, he has returned all of the money and has begun a relationship with "New Parts" Newberg. Though Hank asks Eddie to leave The Hamptons (as he is causing him too much trouble), he decides to stay. He attempts to be a good father to his children, but often misses the mark. He attempts to pull some sort of con on Boris Ratenicz, which later turns out to be spying on him for the Securities and Exchange Commission in return for a reduced fraud sentence. It is a devastating blow to him when he is actually convicted and sentenced to prison. He accepts Boris' offer of escape but in a last-minute change of heart agrees to stay and serve his sentence. In season three, he is conditionally released on a special work program, one of the conditions of which is the wearing of an ankle bracelet and night-time confinement at his sponsor's house–the sponsor in question being his estranged father (Ed Asner). After his successful parole hearing, he decides to remain temporarily in Florida to repair his relationship with his father.
An upper-class girl who pays Evan to pretend to be her boyfriend while she has a relationship with a much older man. She is somewhat domineering, as is her father, who is a retired general. She is also naive, and believes that any problem can be solved by money. She engages in many hobbies befitting her high social status including hunting, painting, golf, and surfing, and has a long list of connections she can call upon.
Her first appearance, "Comfort's Overrated", was when her boyfriend Graham, a man in his 50s, was injured in a surfing accident. She attempts to hire Hank as a "faux-beau", a fake boyfriend to cover from her parents who are questioning her lack of evidence of having a boyfriend. While Hank declines, Evan manages to convince her to hire him, which leads to a day of makeovers and photo shoots. During this, Evan begins to fall in love with her, which Paige fails to or refuses to consider. Graham breaks up with her as he leaves for his African photo shoot, wishing that she did not feel the need to hide him from her parents.
However, her "faux-beau" diversion was still in effect, and in "Frenemies" Evan is taken to meet her parents. When her father blindsides them by taking them to a year-round hunting grounds, and Evan's inadequacy leads to him being (minorly) injured. After realizing Evan's dedication to her, and hearing his heartfelt, unrehearsed speech on her own dedications, she decides to take him out for dinner. After some major ups and downs in their relationship, at the end of the second season she invites Evan to join her in a trip to Europe and at Hank's urging he agrees.
A rival concierge doctor. She is young and overachieving, with an arrogant, perfectionist attitude. She has a podcast and believes in schmoozing her patients much more than Hank does. She is hired by Boris as a substitute for Hank during his (extended) stay in Cuba, and Divya has trouble putting up with her. She later moves to the Hamptons, claiming that the Hamptons are big enough for the both of them, leading to conflict when she attempts to secure her own position through aggressive marketing. She eventually leaves to San Diego during "Big Whoop" to deal with family.
She is more socially, legally and pragmatically, as she refuses to react to calls for a doctor unless she can be sure it would not legally endanger her. Her attitude to medicine leads to many conflicts; rather than using the most medically sound practice, she would rather use a more well-received treatment to keep her patients liking her. Nevertheless, her perfectionism leads to hold all in high standards, including herself; any clinical error she makes she finds distressing. She and Hank carry on a relationship for portions of the second season, but the relationship ends when Emily is either unwilling or unable to share of herself with Hank as much as he hoped.
Jill's husband and a doctor at Hampton's Heritage. He is portrayed as a pompous jerk unable to take no for an answer, yet seemingly liked among the higher staff, where Jill once stated, "through any disaster he has come out of clean, leaving me to clean up the mess". When things do not work out with Jill, she gives him an ultimatum to choose between her and his job, and he chooses his job. When Jill attempts to file for divorce, Charlie flees the country to invalidate it, though when he returns, he hints that he might let the divorce go through, yet he repeatedly postpones signing it to try to woo her. He is alluded to in several episodes, most of the times being brought up by Jill when Hank does something that reminds her of Charlie and makes her believe she is making the same mistake again. Charlie eventually makes an appearance halfway through the first season, when he confronts Jill and gets brambles removed by Hank. He also gets his old job back at Hamptons Heritage. He is trying to win Jill back, which complicates things with Jill and Hank and hinders their relationship for a while. In the first season finale, she kicks Charlie out of her house after he lies to her. It is also revealed he quit from Hamptons Heritage and moved away.
A Cuban doctor who is one of the leading experimenters on Boris's condition. She advocates a risky procedure for Boris that involves a bone marrow extraction, of which Hank disapproves. She and Boris are somewhat amorous, and it is her love for Boris that drives her. When attempting to flee Cuba for the United States, she is arrested. Boris later brings her to the Hamptons, where Hank finds out she is pregnant and that she does not want Boris to know because of his determination that his genetic condition will not be passed on.
Is a former HankMed patient with whom Divya had a brief affair. After kissing him, she immediately confessed to Hank, promising she would never see him again. However, she later returned to treat him, angering Hank. Though Adam still wanted to date Divya, she said she could not, as she was engaged to Raj. The heavily conflicting desires of Divya and the resultant emotional confusion resulted in Adam leaving to film another documentary at the end of "A History of Violins".
