As a primary care clinician, I have the opportunity to develop a trusting partnership with my patients and their families to help them live a healthy lifestyle. I enjoy diagnosing and treating the various illnesses that affect patients during their lifetime, and take great pleasure in seeing them recover. It is important for me to listen carefully to my patients' concerns so we can work together to meet their individual healthcare needs.  

In my free time, I enjoy swimming, running, cycling, and skiing, in addition to spending time with my husband, adult children, and our new granddaughter.

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.

It is a privilege to help people in need get back to being healthy. Individualized care plans and communication are paramount to practicing medicine, I strive to provide the care patients need. Outside of work, I like to try new sports and spend time with family; diligently working to excel in golf.
