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 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.

My focus is to provide patients with knowledge and insight into their specific health conditions.

I pride myself on taking a patient-centered approach to building effective care plans that go beyond the diagnosis of my patients. I am a certified Physician's Assistant who graduated from MCPHS University, Boston with a Master's of Physician Assistant Studies (MPAS.) My previous experience is in primary care and outpatient cardiology. 

Originally from Western Massachusetts, I moved to the South Shore after graduation. I enjoy spending time with my friends, family, and puppy, Oakes. I am also an avid reader and beach-goer. 

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.
