My mission is to engage patients to participate in their medical management.

I enjoy establishing long-term relationships with my patients to enhance their participation in their plan of care.

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.

I chose family medicine so that I could treat a wide spectrum of medical conditions and so that I could treat all ages, including newborns and multiple generations, in one family. This helps me to treat the whole person because knowing a person's social background is essential. I firmly believe that emotional and mental well-being are key factors in maintaining good overall health.

I grew up in Quincy and love living and working near my family and friends. I enjoy spending time at the beach, traveling to exotic places, going out dancing, skiing, cooking/baking, and following Boston sports teams.
