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 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. 
 

It is a privilege to help people,and manage and coordinate exceptional patient care in the hospital. I believe that everyone's medical care should be individually tailored. We all have unique characteristics that need to be considered when deciding a treatment plan. Communication is paramount. Outside of work, I love reading and spending time with my family.

I enjoy caring for children through each stage of development. Promoting lifelong health is important but I also feel confident using medical expertise and resources to support families through acute and chronic illness. Outside of work I love spending time with my husband and two daughters.

Communication is the single most important tool in medicine which I try to achieve every day.

In my free time I enjoy cooking, spending time outdoors, and being with friends and family.
