My focus is to manage and treat patients with a variety of Urologic disorders. I hope to educate them on future prevention of these issues as well. I look forward to assisting in providing surgical treatment for patients with different Urologic cancers.

My interest in medicine was first sparked when my father was diagnosed with esophageal cancer when I was nine years old. I went to Northeastern University for my undergraduate studies and Cornell Medicine for my PA degree. I enjoy playing a variety of sports and spending time with my wife and two kids in my free time.

I chose to become a primary care physician because I cherish the long-term relationships I establish with my patients. I enjoy taking care of patients of all ages and families at all stages of their lives. I believe listening is as important as speaking. I see my role as an educator, sharing my knowledge and helping patients translate that into healthy habits for the prevention and management of chronic illness. 

Outside of work, I enjoy traveling near and far with my husband and three children.

As an admitting hospitalist, my focus is to facilitate a smooth transition between the emergency department and the inpatient  admission. 

Waiting to be admitted to the hospital can be nerve wracking, emotional, and even scary. My goal is to ease  your transition from waiting in the ER to being admitted, explain your condition, and answer all questions you may have. Raised and educated locally, it is my pleasure to serve this wonderful community of people who call the South Shore home. In my free time, I enjoy traveling, spending time with family and friends, and exploring/discovering all that the area has to offer.   

It is an honor to have patients place their trust in my hands. I strive to provide excellent care throughout a patient’s entire hospital stay, be it in the ED, OR, ICU or ward. Outside of work I enjoy spending as much time as possible outside with my family and friends.

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 treatment philosophy is to help educate individuals on their role in disease prevention and develop relationships with patients—working as a team to manage both chronic and acute health issues. I believe that each individual has their own unique set of circumstances that influence their health and working together to overcome barriers is an essential part of providing healthcare. I consider it a privilege getting to know patients and families and always look at the big picture when caring for individuals. Outside of work I love spending time with my family, going to the beach, gardening and hiking. I am teaching myself how to ice skate so I can play hockey with my boys! 

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 goal as a physician is to help patients learn about the importance of following preventative measurements and living a well-balanced life to tackle many diseases before they become debilitating illnesses.

I am excited to be part of the South Shore Hospital Medicine team. I believe patient education and communication are the key components to provide the best possible care to all my patients. My training has helped me master the skills to provide evidence-based, culturally competent, and patient centered care to all my patients. It is my honor to be able to provide you the needed medical care while you are admitted to the South Shore Hospital.

Outside of work, I love hiking, painting, and exploring different places.
