Shelly is a nurse at Sacred Heart Hospital.
When Dr. Kelso rehired Nurse Patti, Shelly was seen thanking him for his kind deed, even though it was him who fired her in the first place. ("My Way or the Highway")
The next year, Shelly laughed at J.D. when Carla spread the rumor that he was running kissing drills with Rowdy. ("My T.C.W.")
