I'm a Senior Network Physician practicing at Dana-Farber Community Cancer Care in Weymouth. I am certified by the American Board of Internal Medicine in Hematology, Medical Oncology and Hospice and Palliative Medicine.  I received my BA from Oberlin College and my MD from Tufts University School of Medicine.  I did my training in Internal Medicine at Boston City Hospital and her Hematology-Oncology training at New England Medical Center. In my free time, I enjoy traveling, music and outdoor pursuits.

My treatment philosophy is to establish good rapport with patients during their difficult moments, and to focus on shared decision-making while working on treatment plans and management of acute issues.

I have been practicing medicine for more than 20 years now. I like communicating with patients while focusing on their medical issues and helping formulate plans to meet the treatment needs. Apart from medicine, I enjoy spending time with my two boys, cooking and baking. I am an avid nature lover and enjoy hiking. Exploring new places brings me true happiness. Yoga and meditation helps me unwind after hectic days. 

It is such an honor and privilege to be a physician.  It has been especially gratifying to devote my career to the field of Hospital Medicine, and to work at South Shore Hospital to help serve my community. 

Being hospitalized is often one of the most challenging and frustrating experiences a person can have. As a Hospitalist, what is so rewarding is that I can use my training and abilities to make such difficult times for people more compassionate and less confusing. 

Outside of the hospital, I love spending time with my wife and young son and traveling.  I also love anything to do with the outdoors and enjoy running.

My goal is to educate, support, and empower women to make choices about their health that they feel good!

I believe in providing women with education and options that empower them to make healthy decisions that contribute to better health for themselves and their families. I see the importance and benefit in a model of shared decision making. When I'm not midwifing it up I like to write, read, run, bake and hang with my kids and husband!

I also blog for South Shore Health. Check out my blog posts!
