I chose family medicine so that I could treat a wide spectrum of medical conditions and so that I could treat all ages, including newborns and multiple generations, in one family. This helps me to treat the whole person because knowing a person's social background is essential. I firmly believe that emotional and mental well-being are key factors in maintaining good overall health.

I grew up in Quincy and love living and working near my family and friends. I enjoy spending time at the beach, traveling to exotic places, going out dancing, skiing, cooking/baking, and following Boston sports teams.
