I enjoy caring for children through each stage of development. Promoting lifelong health is important but I also feel confident using medical expertise and resources to support families through acute and chronic illness. Outside of work I love spending time with my husband and two daughters.

Prior to joining Cohasset Pediatrics I practiced pediatrics south of Boston for nine years and was Chief of Pediatrics for four years within that practice.  

I received my undergraduate degree in Drama from New York University’s Tisch School of Arts.  Working as an actress afforded me the opportunity to travel professionally and experience life as a performing artist in New York City, Los Angeles and London. While working in show business was certainly exciting, I found my true calling working as a physician partnering with parents to help provide the best medical care for their children.

When not at work, I love spending time with my husband and two children and enjoy singing when I get the chance.

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.
