I consider myself lucky to do something that I love. Children and teens are great at reminding adults about the little joys of life while also presenting us with various medical and behavioral challenges. I enjoy navigating these challenges with each family to find the right approach for their child. Outside of work, I love spending time with my husband and three (lovable and challenging) children. I enjoy running with my dog, biking, swimming, skiing, and occasionally a good day of yard work. 

Treatment of disease begins with a correct diagnosis, using all of the available clinical and laboratory data available. While we do not have the same visibility to the patient as their primary care provider or surgeon, pathologists are an integral part of every patient's health care team, assuring that their physicians have accurate and timely pathology and laboratory data on which to act.  Away from the office, I'm a singer and cellist - you can find your way to my office by following the music.

I strive to provide excellent care to my patients and to help them understand their conditions through education.

As a rheumatologist, my goal is to take care of my patients as individuals and to work together with them to find the most effective treatment plan. I am passionate about helping patients with rheumatologic conditions find relief with the therapies we have available today. Outside of work, I enjoy playing tennis, exploring new restaurants, and spending time with family and friends.

My mission is to partner patients to improve health outcomes and experiences with healthcare.

Entering the health care field has been a great joy and privilege. Working with patients for over 10 years has illustrated that everyone's needs are unique. Communication and respect are the backbone of a positive provider patient relationship. When I am not working you can find me spending time with my husband and three children outside and at the beach as much as possible.  Paddle boarding and collecting seashells are our favorite activities.

I find great satisfaction in treating the whole person and not just their illness. Understanding a patient's unique outlook on life is paramount to providing proper care. Each patient has a voice which should not only be heard but appreciated.

Outside of work, I enjoy time in the woods; hiking, fishing and kayaking with family and friends. 

I will do my best to take care of you.

I started the PA program at Northeastern University in October of 1988. Since first picking up a stethoscope, I have loved being a PA. Many of my patients have shown courage and dignity at a most vulnerable time in their lives, often with good cheer. 

Great joys in my life include grand babies, my chubby cat, dog walks and kayaking at sunset. My passion project is making stained glass panels which feature birds, fish and animals in their natural habitat.

I feel privileged to care for patients from age 18 to 95 and beyond. While I base my practice firmly on research-based evidence, I am aware that much is still unknown in medicine and that guidelines evolve over time. Open communication with my patients helps me respect patients' values and health goals.

Outside of work, you can usually find me exploring the beauty of nature with my four young children.

I am the Medical Director of Population Health for South Shore Health and divide my time between administration and patient care. My administrative interests include integration of care, professional development, and community centered program development. I value long-term relationships with my patients and find it a privilege to care for patients over their lifespan.

I care for women throughout their lives—from adolescence through adulthood. I especially enjoy building long-term relationships and being with my patients through each step of their lives. From routine gynecological care to preconception, pregnancy, post-partum and menopause, I am here for my patient throughout her life. I chose OB/GYN as my specialty for the diversity of practice. It involves medical care, surgical care, and delivering babies. 

My parents inspired me—my father was a surgeon and my mother a nurse. I initially wanted to forge a different path and received my bachelor’s degree in Economics. I worked in financial public relations for a short while, but I kept coming back to what really interested me: medicine. I eventually went back to medical school to pursue my true passion. Outside of work, I love being outdoors—hiking, biking, boating, paddle boarding, and snowboarding. I also love to travel and spend time with my family and beloved dog and in quieter times enjoy reading and knitting.
