 Jonathan L Hoffman, DMD

I grew up in Longmeadow, MA, a beautiful small town in the western part of the state. I attended the University of Massachusetts in Amherst, earning a bachelor’s degree in Biology and Pre-Dental studies. Immediately after college, I moved to Boston where I conducted clinical research trials at the Tufts University School of Medicine, and was published in many reputable journals. I earned my Doctorate in Dental Medicine from the Tufts University School of Dental Medicine, and also completed an optional year-long dental residency in Advanced General Dentistry in Maui through the Lutheran Medical Center. I spent a total of two spectacular years in Hawaii before coming back to Massachusetts with my wife, Marcia (a Westborough native!) to start both my career and my family. Now a proud father of 3, I enjoy spending my free time with my family, coaching sports, attending community events, and playing the occasional round of golf. I also play the saxophone in the Westborough Community Band every summer! I look forward to taking care of you and your family’s oral health care needs.

Dr. Hoffman is a member of the American Dental Association, Massachusetts Dental Society, and the Worcester District Dental Society. He has participated in community dental health care through KidSeal, and enjoys visiting the local schools and pre-schools to educate children of the importance of oral and general health.
