A hospitalization is often wrought with difficult news and decisions; it is my honor to care for patients at these times. I enjoy working with a care team, to deliver high-quality care. Above all, I try to foster sincere relationships with patients, focusing on what is most important to each person.   

My mission is to provide culturally competent, evidence-based, and compassionate care to improve the quality of life of all of my patients. 

Medical care that not only tends to patients’ physiological ailments but imparts a sense of emotional comfort is the preeminent force in my practice. I completed my training at Tufts University School of Medicine, where I received a Masters Degree in Medical Science and another Masters Degree in Public Health.

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 have been a physician's assistant in women’s health for close to 30 years on the South Shore. I enjoy seeing women in their many phases of life. I feel privileged when patients I met at the start of my career bring their daughters and granddaughters in to see me for their care. When not working, I enjoy spending time with my family.

I've worked in the pediatric health care field since high school and by the time I went to college, I knew it would be my career. Children are all different, there is no lock and key to the care and respect they deserve. It's been an honor working with so many wonderful patients and their families, especially watching them grow and take on new aspects of life. Outside of work, I love the outdoors, gardening and traveling with my husband.

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.
