I came to medicine from the business world, and it has been incredibly rewarding to focus my energy and abilities on helping people who are acutely ill. I believe that really listening to patients and their families is the key to providing exceptional care. Outside of work, I enjoy spending time with my wife and two young children.

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.
