About UMass Fitchburg:  "After 19 years of clinical practice before coming to UMass, I maintain a passion for community service and for the care of patients with a focus on health maintenance and systems implementation to enhance safe, accessible, comprehensive service. When I made the move to UMass, I shopped for a residency that was community-oriented and expressed care for its members, patients and staff like family. I found what I was looking for in Fitchburg!" 
Personal Facts: "My wife Lauren keeps my life in balance and my three children keep me active. Hobbies (often conflicting) include good food, reading, fitness, visiting the Cape, and protecting my home from the enthusiastic exploration of our new lab pup, Cassie. One day, with no kids' sports and school events, and with house renovations completed, I'll dust off my golf clubs or perhaps join another medical mission team."
