My philosophy is to listen carefully, ask the right questions, and offer my expertise within the scope of my skills.

I was born in New York City to immigrant Latino parents. Yes, I root for the Yankees, of course!

Outside of work, I enjoy physical fitness and spending time with my family. 
 

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.
