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. 

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.
