It is a privilege to treat patients compassionately in our community. I strive for excellence, open communication, accessibility, and long-term relationships. Outside of work, I especially love spending time with my family, swimming, bicycling, tennis, golf, sailing, photography, and magic.

I grew up in southern Maine and attended Harvard University for my undergraduate education. While at Tufts University School of Medicine and Mount Auburn Hospital in Cambridge, my focus was on primary care medicine. I believe in the dignity of each of my patients. Respect, compassion, and reliability are among my goals in patient care. In my free time, I enjoy the outdoors and the arts, usually in the company of 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.
