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.

My mission is to give the same care to my patients as I would want for my family or myself.    

I was born and raised in the Boston area.  After a long period of schooling and training across the country (New Hampshire, Ohio, California, Pennsylvania), I have been honored to return home to take good care of my people!  When not fixing retinas, I enjoy spending time outdoors with my wife and three children.   

My mission is to provide exceptional care to hematology and oncology patients, and support patients and their families when they are at their most vulnerable. 

It is a privilege and an honor to have the opportunity to establish meaningful, long-term relationships with my patients and their families. I believe in open, honest communication and a patient-centered model when formulating a treatment plan. I look forward to supporting my patients not only physically, but mentally and emotionally as well. 

Outside of work, I enjoy spin classes, going to the beach, and spending time with family and friends. 

I am a dedicated and patient focused physician with comprehensive experience in hospital settings. I hold a great regard for detail, accuracy and follow through and can make decisions in a fast paced and unpredictable environment. I value communication with patient, their families, my colleagues and support staff to provide very best care for our patients.

I enjoy getting to work with patients in the inpatient hospital setting. As a hospitalist, I am able to work collaboratively not only with the hospitalist team itself, but also with specialists, nurses, case managers and all of the hospital staff. I appreciate being able to build relationships with patients as well. I enjoy the variety and challenges that come with working as a hospitalist. Outside of work, I enjoy spending time with family and friends and I am a fan of the Patriots, the Celtics and U.S. Soccer.
