I completed my Master’s Degree as an Adult Nurse Practitioner at Northeastern University and earned my bachelors of Science degree from The College of the Holy Cross as a Biology Major and Philosophy minor. I worked as a registered nurse at MGH on a cardiac step down unit and then an NP in a busy nursing home practice and in two community health centers. I enjoy being active and spending time outdoors with my husband and two children.

I strive to build a space where patients feel safe to discuss their health concerns and engage in shared decision-making.

Prior to joining South Shore Health, I had the privilege to train at UMass Family Medicine Residency and complete an additional year of fellowship to also care for patients living with HIV/viral hepatitis at the Family Health Center of Worcester.

Outside of work, I love spending time with my family, running, gardening, and camping/hiking.

My mission is to provide the best primary care for my patients to prevent disease. This includes regular follow up of chronic conditions and keeping patients up to date with routine screenings.

It is a privilege to provide primary care and establish long-term relationships with my patients. I believe that everyone's medical care should be individually tailored, and communication is key to providing excellent care. Outside of work, I love to spend time with family and friends. My hobbies include skiing, quilting and cooking. 

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.
