Dr. Keith Dudemeister

Dr. Keith Dudemeister is a doctor working at Sacred Heart Hospital. He began as an intern the first year that J.D. and Elliot were attending doctors and was a member of J.D.'s group of interns. Elliot soon began using him for convenient sex, but shortly after they became a real couple. He proposed to her the following year and she accepted. Months later she returned his ring because she realized she didn't love him. He continued to work at Sacred Heart, resenting her. Keith is an affable and attractive doctor, and his trust in other people can sometimes lead him to uncomfortable situations. As he became a more confident doctor, he also became a more confident person.
Keith is portrayed by Travis Schuldt and appears in 39 episodes of Scrubs in seasons five, six, seven, and eight. His character first appears in "My Intern's Eyes", but Travis Schuldt isn't seen until the following episode "My Rite of Passage". He was last seen in J.D.'s final fantasy in "My Finale" and is presumed to still be working as a doctor.
