Having grown up on the South Shore, it is a pleasure to care for patients of this region. I served in the US Navy following medical school and completed my surgical training through the Navy. Following multiple military assignments, I chose to return to the area in order to serve my local community and reside closer to 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.

I strive to provide excellent care to my patients and to help them understand their conditions through education.

As a rheumatologist, my goal is to take care of my patients as individuals and to work together with them to find the most effective treatment plan. I am passionate about helping patients with rheumatologic conditions find relief with the therapies we have available today. Outside of work, I enjoy playing tennis, exploring new restaurants, and spending time with family and friends.

It is truly an honor to participate in the care and lives of my patients. My passion is driven by the bonds I build with my patients over the course of their lives and the enjoyment and satisfaction I hold in treating them to be as healthy and pain free as possible. It is to the extent that I feel that  "I truly have the best job in the world."

I partner with women to provide education, resources and choices regarding their bodies, healthy pregnancy, labor and birth. It is a privilege to care for women and families and to be present at their birth. Each labor and birth are unique. Even after 33 years as a midwife, I am amazed at the beauty of birth and the strength of women.

I started the first midwifery practice at South Shore Health in 1987 and have enjoyed being director and now co-director of the midwifery group and watching our program grow over the years. Outside of work, I love spending time with my husband and children. I also love running my dog on the beach, paddleboarding and gardening.
