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. 

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 grew up in Scituate and am a proud graduate of Scituate High School.  After graduating from Harvard-Radcliffe, I continued doing another year of diabetes research at Massachusetts General Hospital, then did two years of breast cancer research at the Dana-Farber Cancer Institute.  I graduated from the Boston University School of Medicine, went to UMass Worcester for residency, graduated from the Harvard School of Public Health, and then went to Brown for residency.  I began working at South Shore Medical Center in 2008.  I especially enjoy seeing patients who knew my father, a police officer in Scituate for 29 years and hearing their stories about him.  I try to motivate, encourage and work with my patients and it is an honor and a privilege to be able to care for them.  Outside of work, I love dancing, playing frisbee, and spending time with my family. 

My job is ultimately about the trust that comes from a long-term relationship.  I am honored that people choose me to care for them and their extended families, and I do my best to give thoughtful and evidenced based advice.  Each of us has unique goals for our long term health, and I really enjoy giving people guidance in this realm.  I also enjoy the challenge of my work.  Each day is extremely diverse and forces me to stay continually current.  When I am not at work, I love competing in triathlon and cycling events, skiing, travel, and being outside.  I also adore being a father to my three daughters.

I love caring for children and their families, whether it be supporting parents as they learn how to care for their newborns or helping a sick child recover from an acute illness. I believe in shared decision-making and incorporating each family's individual needs and goals into their child's care. Outside of work, I enjoy spending time with family, running, and traveling.

I am originally from Cambridge, Massachusetts. I practiced in Quincy for 30 years before coming to South Shore Medical Center in 2002. I am experienced in abdominal surgery, trauma, and management of skin and soft tissue tumors. 

I strive to educate patients about their health conditions in order to best include them as part of the treatment team.

Brendan has spent a large portion of his career practicing in Primary Care following graduation from MCPHS University in 2014.  Having grown up in Massachusetts, as well as living and working in Southeastern Mass he has formed close relationships with his patients as they are frequently his neighbors, mechanics, former teachers and the like. From these relationships, he has learned the importance of community as part of a medical treatment plan, and this has now become an important aspect to the way he practices medicine. He is very excited to extend his medical career into the South Shore Health Community. 

I strive to build a space where patients feel safe to discuss their health concerns and engage in shared decision-making.

Prior to joining South Shore Health, I had the privilege to train at UMass Family Medicine Residency and complete an additional year of fellowship to also care for patients living with HIV/viral hepatitis at the Family Health Center of Worcester.

Outside of work, I love spending time with my family, running, gardening, and camping/hiking.

I try to have a collaborative approach to disease management and prevention, with an eye towards the most value for the patient's dollar.

I have been lucky enough to be a family physician since 2010. Since then, I have worked to provide cost-effective and compassionate care for my patients. I'm also committed to advocacy for my patients and fellow MD's outside the office, though my role on the Massachusetts Academy of Family Physicians. I enjoy traveling, hiking, gardening, and computer gaming, when my young children allow any of them.
