She has the distinction of being one of the few characters on the show (Dr. Wilson being the other) who can match wits with the fast-talking Dr. House in conversation (and arguments) and be considered one of his "friends". She often is left to pick up the pieces of House's questionable medical practices. She is also one of the few people who can stand House's rude manner, strange requests, and his many obnoxious (sometimes nosy) habits. Although she frequently criticizes House's methods, she does trust his decisions to be in the best interest of his patients. Over the course of the show, it is seen that she is one of the few, if not only, people who would hire House at all, due to widespread disapproval of House's results-oriented methods and constant insubordination. A developing arc in season five indicates that she has (and may have always had) very strong feelings for House; in season five's "Saviors" she refuses to answer when asked if she is in love with House, dismissing it as "a ridiculous question." House has described her as a Second Rate doctor. In season seven Cuddy and House started dating. She leaves the hospital after Dr. House drives his car into her house, and she is replaced by Dr. Foreman in the beginning of Season 8.

Wilson claims that his job and his "stupid, screwed up friendship" with House are the two most important things to him. He, along with Dr. Cuddy, usually finds himself aiding and abetting House's Vicodin addiction and his very unorthodox methods.

    , Dr. House tells Foreman that a major factor in his hiring was the fact that he was a former juvenile delinquent who once stole cars and had 'street smarts'. As a result, he frequently voices his disapproval of House's maverick methods and daring decisions. Foreman resigned at the end of Season 3, feeling that the more time he spent with House, the more he became like him. Foreman then took a position as Head of Diagnostic Medicine at New York Mercy Hospital. During that time, he saved a patient's life by going against their protocols, something that House frequently does. Foreman is then told that while he may have saved the patient's life, he cannot be there if he cannot be trusted to obey his senior medical officers. Foreman is then fired. Although he applied at other medical facilities, no one would hire him because of the incident, attributing it to his past association with House. He later returned to Princeton Plainsboro because Cuddy was the only person willing to hire him after his actions. At the beginning of season 6 he was made Department Head of Diagnostic Medicine after House quit. He becomes the Dean of Medicine after the departure of Dr. Cuddy in the beginning of season 8.

    , whose subsequent death had a lasting impact on her. In the first season, she has a flirtatious relationship with House, but eventually embarks upon a tenuous affair with Robert Chase. Cameron resigned at the end of Season 3, but returned in Season 4 as a member of the Princeton Plainsboro Emergency Room staff. She does eventually marry Dr. Chase, although ends up divorcing him after he intentionally killed a patient who happened to be the dictator of a war-torn third world country, stating that Chase, like House, had no regard for the sanctity of life.

    ) – Surgeon, intensive care specialist. Dr. Chase's demeanor appears to have been either influenced or amplified by House, as he has previously displayed a penchant for insulting patients behind their backs, takes clear and vicarious joy in watching House tear into others, finds House's antics more amusing than others do, and repeats House's mantra of "everybody lies" whenever a patient's full disclosure of any required medical history is called into question. Moreover, when suggesting treatments to diagnoses, Chase is arguably the most creative member of House's staff, often proposing unconventional treatments that had not previously been considered, but whose perceived effectiveness is generally agreed upon. Chase was fired by House at the end of Season 3, but he returned in Season 4 as a member of Princeton Plainsboro's surgical staff. He is infamous for his intentional killing of President Dibala, an African dictator the team treated, which ended up killing his marriage and causing him almost endless amounts of guilt despite him claiming it was the right thing to do, as Dibala would have massacred his Sitibi countrymen had he survived.

Seasons 1–3

The original diagnostic team consisted of Dr. Cameron, Dr. Chase and Dr. Foreman. While both of their tenures had brief interruptions, Chase and Cameron still appear semi-regularly on the show. They advise the newer fellows in the Diagnostic Department in seasons 4–5, or participate in cases directly when appropriate.

Vogler sought to reshape PPTH into a testing facility for his firm's new drugs and saw House's maverick ways and blatant disregard for rules and authority figures as a substantial legal and financial liability.

, so to speak, to Vogler's increasingly capricious demands (including an order for House to fire one of his fellows) and made a mockery of Vogler's company at a press banquet, Vogler gave the board an ultimatum: fire House, or lose Vogler's grant. After an impassioned motion from Cuddy for the board members to put the hospital's independence ahead of Vogler's donation, the board voted to retain House, as well as voting Vogler off the board of directors and therefore losing his $100 million.

Fox demanded a bad guy to be added to the show, a few months before House went on a Christmas hiatus. Shore opposed Fox's request, because he thought adding such a character would be a bad idea. Although Shore thought he managed to convince the producers not to add the character, during his vacation in Israel

, threatened to cut the season short by six episodes unless the character was added. To prevent this from happening, Shore created the character. McBride was hired to film five episodes. However the producers decided not to extend the character's story arc. In a video David Shore said: "Chi McBride is so larger than life. He’s literally just a physically imposing person, and we just wanted someone who could really clash with [House], somebody who could be emotionally and physically and psychologically imposing as he is and could go head to head with him."

 graduate. Two years after their breakup, she married Mark Warner. She appears in 9 episodes during the run of season 2, taking a job at PPTH (after asking Cuddy to make sure it was okay with Gregory House) to be close to her husband during his recovery.

House and Stacy's relationship has been strained due to his relentless attempts to prove she still has feelings for him. Mark aided House's cause by driving a wedge between himself and his wife when he suspects a brewing affair. Mark was eventually proven correct, as Stacy fell for House all over again and they slept together. As Stacy prepared to leave her husband for House, he then rejected her (stating that he could not make her happy, because he could not change). She quit her job at the hospital and went back home to Short Hills

 with Mark. An enraged Wilson believed House broke her heart not out of guilt for Mark (which is not his modus), but as a last-ditch resort to ensure that House does not allow himself happiness. The aftermath of this botched affair left House in a stark depression. Stacy has not appeared on the show since.

In the episode "Son of Coma Guy", when playing a questions game with a patient to make a diagnosis, House admitted that he had been in love once. He said they met when she shot him in a game of paintball, Doctors vs Lawyers. Presumably, House was talking about Stacy. When the patient asked if that was the only time he'd ever been in love, House avoids answering and changes the subject.

) is one of House's clinic patients. After House refuses to run tests at Tritter's request and insults him, Tritter trips House. House agrees to the tests and tells Tritter he has to check his temperature to rule out infection. House proceeds to use a rectal thermometer, and his supposed reason for using the rectal thermometer over a normal mouth thermometer is Tritter's chewing of nicotine gum, since oral readings can be affected by food and drink. House then leaves the room on a pretense with the thermometer still inserted in Tritter's rectum; House intentionally never returns and Tritter endures the rectal thermometer for two hours.

Afterwards, Tritter demands an apology from House for deliberately leaving the thermometer in him. House refuses, apparently spurred on by the patient's attitude, which is as bad as House's. Caught speeding and arrested for possession of allegedly unprescribed medication, House is thrown in jail overnight by Tritter, who searches his house the next week and finds a large amount of Vicodin. He also interviews House's staff looking for inconsistencies in their stories. He proceeds to tighten his vise grip on Wilson by freezing Wilson's bank account, towing his car, and revoking his drug prescription rights because he wants Wilson to testify against House in court.

After Tritter discovers that Wilson refuses to betray House, he turns on to House's assistants, freezing Foreman and Cameron's accounts, before talking to each one of them in turn. Foreman and Cameron refuse to testify in court about House, but when Tritter talks to Chase, he makes it appear to the hospital staff as though they had had a pleasant lunch together. Chase is concerned that this makes Foreman and Cameron think that Chase has told Tritter something, although he had refused to, his only stated reason being that he would lose his job.

Tritter finally succeeds in his goal when Wilson comes to him, requesting "thirty pieces of silver" in a symbolic statement of his decision to betray House, whom he has come to see as spiraling out of control. In the final days leading up to House's trial, House enters rehab. Tritter confronts him in rehab to see if he was really going through with it. When the charges against House were dropped at the trial, because Cuddy fabricated evidence that acquitted House, Tritter wished House good luck and said that he hoped he was wrong about him. Tritter has not appeared on the show since.

Volakis is willing to do anything to get the job, including acts of dishonesty. This is first seen when she convinces a group of applicants to quit, rather than be humiliated by House; she returns moments later admitting it was a ruse. She is subsequently referred to as "Cutthroat Bitch" and "Bitch" by House throughout the season, and is even referred to as such on House's caller I.D. After the characters stop using this nickname, she is still almost always called by her first name, unlike the rest of the characters. She sometimes coerces Chase and Cameron, now reassigned to different departments of the hospital, into helping her. Her persistence and unorthodox approaches initially win her praise, but she is ultimately eliminated because House feels she cannot accept being wrong, something he says she would need to be able to accept on a regular basis if she were to work for him.

Dr. Volakis returns in "Frozen" when House discovers that she is Wilson's new girlfriend, a fact Wilson had been trying to conceal from House. House and Amber quickly develop an adversarial relationship, bickering over "shared custody" of Wilson. In the two-part season 4 finale (episodes "House's Head

However, this proves almost fatal to the patient at the time when House gets the diagnosis wrong and almost kills Chase at his bachelor party (inadvertently causing him anaphylactic shock when he licks a stripper covered in strawberry flavored body butter – Chase suffers from an allergy to strawberries).
