Doctor Elliot Reid is a former attending physician alongside J.D. and Turk at Sacred Heart in Scrubs and is played by Sarah Chalke. Elliot is very close with J.D. and has an off-and-on again relationship with J.D. throughout the series. She has also dated several other characters including Sacred Heart doctor Keith Dudemesiter, to who she was engaged to and later broke off the engagement.
Elliot later went into private practice where she was able to make much more money, but still work at Sacred Heart but no longer have to respond to Dr. Cox or Dr. Kelso.
Elliot is extremely insecure and very socially awkward. She, though is attractive, and slowly becoming more confident throughout the seasons.
Elliot: Okay, rocktors - heh, that's my name for doctors who rock next patient!
J.D.'s Narration: Ever since her fellowship, Elliot loved that her interns saw her as an endocrinology expert.
Male Intern: Dr. Reid, why would Mr. Baum develop new onset diabetes and high blood pressure simultaneously?
Elliot: Well, as an endocrinology expert, heh, in my expert opinion, both can be expertly explained by a pituitary adenoma causing Cushing's syndrome.
Dr. Cox: Hate to burst your bubble, there, Barbie, but your endocrinology fellowship lasted all of five days. Granted, to you, five days may seem like an eternity seeing as it's roughly five times as long as any of your white, pasty relationships have lasted. But trust me, that hardly makes you an expert.
Elliot: Dr. Cox never compliments me about anything!
Janitor: Well, he should. Your new look has completely changed my perspective. For instance, this is not a broom with fraying edges - this is now a broom that reminds me of blonde doctor's bangs. Tough and spunky!
Elliot: Oh, my God! That is exactly the look that I was going for!
