Department of Medicine


759 Chestnut Street, S2570
Springfield, MA 01199

Welcome from the Chair

We pride ourselves on providing the highest quality, patient-centered care, and on being a nationally recognized leader in medical education.  The Department consists of 13 subspecialty divisions comprising over 160 physician specialists and 80 advanced practice clinicians.

We educate more than 100 residents and fellows every year; our internal medicine residency is one of a select few in the U.S. to receive the prestigious Educational Innovations Program designation.  As the regional campus of the University of Massachusetts Medical School and Tufts University School of Medicine's largest clinical training site, we educate dozens of medical students annually.  Our faculty and residents are actively pursuing medical research that is transforming the way in which we deliver healthcare to the communities we serve.

I invite you to learn about more about our education and research activities.  I am confident you will discover the richness and quality that define the Baystate Health Department of Medicine.
