Bio
I grew up in MA and now live here with my family. After completing my education in New Hampshire, Maine, Rhode Island and New York, I was able to return to MA. Since returning to MA I have worked in a couple of large Cardiology groups in different locations. This past year I was finally able to open my own practice and I am looking forward to providing good medicine in a comfortable setting. Heart disease can be difficult to treat and frightening for the individual and families affected. We are trying to make it less stressful for all affected.
