It is such an honor and privilege to be a physician.  It has been especially gratifying to devote my career to the field of Hospital Medicine, and to work at South Shore Hospital to help serve my community. 

Being hospitalized is often one of the most challenging and frustrating experiences a person can have. As a Hospitalist, what is so rewarding is that I can use my training and abilities to make such difficult times for people more compassionate and less confusing. 

Outside of the hospital, I love spending time with my wife and young son and traveling.  I also love anything to do with the outdoors and enjoy running.

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.
