Pediatric Residency Program - Who We Are

Our residents are our program’s greatest strength. While they come from incredibly diverse backgrounds personally, academically, and geographically, they also share many characteristics. Friendly and social as a whole, our residents are deeply committed to patient care and hold themselves and each other to the highest standards. Each class shares a strong sense of camaraderie and trust that develops quickly from their common experience.

The residency is led by our Program Director and Associate Program Directors, who are dedicated resident advocates. Three Chief Residents and two Program Coordinators organize resident education and provide the bridge between residents and faculty. Flexibility is a key characteristic of the program, and all residents have the opportunity to provide input in program development.
