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.

Having grown up on the South Shore, it is a pleasure to care for patients of this region. I served in the US Navy following medical school and completed my surgical training through the Navy. Following multiple military assignments, I chose to return to the area in order to serve my local community and reside closer to my family. 

Establishing a good patient-physician relationship is crucial to help provide the best care. I believe in allowing ample time in a visit to listen to my patients' needs and thoroughly explain their diagnosis and treatment plan. Most podiatric issues can be treated with aggressive conservative therapy, although when surgical intervention is necessary, I will communicate that to the patient in a direct and concise manner. 

My mission as an emergency department physician is to provide timely and excellent care to patients while helping them through what are likely very stressful and difficult emergency situations.

I grew up in southern New Hampshire and attended Providence College in Rhode Island. I then obtained my MD at the University of Connecticut. I completed my emergency medicine residency at the University of Cincinnati and while I loved the Midwest, I always planned to come back to New England and was happy to move to the South Shore. In my free time I enjoy hiking, skiing, and spending time with family and friends.

Dr. O'Brien is Medical Director of Maternal-Fetal Medicine at South Shore Health. 

As a Maternal-Fetal Medicine physician, I am dedicated to caring for women and families navigating high-risk and medically complex pregnancies with expertise, compassion, and individualized attention. 

I strive to integrate evidence-based medicine with a holistic approach that recognizes the physical, emotional, and social factors that shape each patient’s experience. 

I am also committed to advocating for equitable healthcare and improving access and outcomes for marginalized and underserved communities.
