Internal Medicine Residency Program
Housestaff & Chief Residents

Families thrive in supportive, welcoming atmosphere
The Winthrop housestaff finds the Department of Medicine an ideal place to work and learn during the stressful years of residency training. Families tend to thrive in a supportive Winthrop environment. The composition of the housestaff is as diverse as the community it serves, with the common denominator being an interest in clinical practice and research.


Chief Residents

The Chief Residents are PGY-4 medicine graduates of the program selected for excellence in clinical skills, leadership, and scholarship. Their day-to-day teaching, leadership, and advocacy for the housestaff is a strength of the program.

The Chief Residents are chosen in the fall of their PGY2 year giving them the opportunity to strengthen the skills needed for their future position and career planning.

The current and incoming Chief Residents will be available to meet with prospective candidates upon interview.
