Christopher Duncan Turk aka Turk

Christopher Turk, commonly referred to by his surname, is the best friend and former roommate of the series' protagonist, J.D. He is currently an attending surgeon at Sacred Heart Hospital, where the series takes place, and is married to Carla Espinosa, one of the nurses. He was most likely born somewhere around 1976, as he first left for college in 1993/1994, during which time, as well as completing his pre-med requirement, he completed a minor in Psychology. In "My Bad", he reveals that he regularly attended therapy during this time in order to deal with the stress.
Turk is a very competitive person. He says that his competitive nature drove him to "play everything" in high school, and he also cites it as the main reason why he became a surgeon. He can frequently be seen throughout the series playing basketball outside the hospital, which helps him to relax before he has to perform surgery, or engaging J.D. in childishly competitive games. J.D often doesn't really want to participate in the games Turk challenges him to. Turk is normally the victor of these games, and he enjoys rubbing it in J.D.'s face. He normally does this by making J.D. say "I'm your biatch" after J.D. loses.
In "My Cake" Turk is diagnosed with type two diabetes; he at first takes it as a joke, but now takes it seriously.
Turk is Roman Catholic, though his faith is tested in the episode "My Own Personal Jesus" by numerous casualties occurring on Christmas Eve. His faith is restored at the end of the episode by his miraculous finding of a missing pregnant girl in severe need of medical attention.
As evidenced by "His Story IV", Turk appears to be a political liberal; he votes Democrat and does not support the war in Iraq. He is also frequently seen wearing Amnesty International t-shirts. He states in a deleted scene of "My Way Home" that he is a Democrat.Along with being a gifted singer, Turk is an extremely talented dancer. In "My Half-Acre", he becomes a member of the Cool Cats, the hospital air band put together by the Janitor, Ted Buckland, and Lloyd, the hospital's delivery man. He also seems to be very attracted to Tyra Banks, admitting he has a picture of her in his cell phone.
