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 feel privileged to care for patients from age 18 to 95 and beyond. While I base my practice firmly on research-based evidence, I am aware that much is still unknown in medicine and that guidelines evolve over time. Open communication with my patients helps me respect patients' values and health goals.

Outside of work, you can usually find me exploring the beauty of nature with my four young children.

I want each patient I care for to feel heard, safe, well-informed and active participants in their healthcare.

Midwifery has been an (almost) lifelong passion of mine. I saw my aunt give birth to my cousin when I was 10 years old and knew instantly that caring for women and babies was what I was meant to do. I started as a labor and delivery nurse in 2011 and completed midwifery school in 2015. I have attended births in the hospital and home setting. I love caring for women in pregnancy and all other stages in their lives. In my free time, I enjoy hanging at our family beach house on the Jersey Shore, snowmobiling in Pittsburg, NH and spending time with my husband and 2 daughters. 

I enjoy helping people stay healthy through preventative medicine, as well as treating both developing and ongoing health issues. I especially value getting to know my patients over time.

My focus is to provide patients with knowledge and insight into their specific health conditions.

I pride myself on taking a patient-centered approach to building effective care plans that go beyond the diagnosis of my patients. I am a certified Physician's Assistant who graduated from MCPHS University, Boston with a Master's of Physician Assistant Studies (MPAS.) My previous experience is in primary care and outpatient cardiology. 

Originally from Western Massachusetts, I moved to the South Shore after graduation. I enjoy spending time with my friends, family, and puppy, Oakes. I am also an avid reader and beach-goer. 

My mission as an emergency department physician is to provide timely and excellent care to patients while helping them through what are likely very stressful and difficult emergency situations.

I grew up in southern New Hampshire and attended Providence College in Rhode Island. I then obtained my MD at the University of Connecticut. I completed my emergency medicine residency at the University of Cincinnati and while I loved the Midwest, I always planned to come back to New England and was happy to move to the South Shore. In my free time I enjoy hiking, skiing, and spending time with family and friends.

As a medical student, I was unsure what my clinical focus would be. Once I saw my first delivery, it was clear that this was my future. I started my internship and residency training here in Boston. After moving to California and spending several years practicing there, I knew I wanted to return to Massachusetts. I have been at South Shore Hospital for nearly ten years now and am grateful to work with the women of the South Shore. After many years practicing both Obstetrics and Gynecology, I realized my true love was the Birthing Unit and transitioned to a Laborist position. I am privileged every day to be part of something so amazing and love that I get to share in such an important family experience.

My treatment philosophy and ultimate goal is to collaborate with families to achieve the best birth experience while helping to ensure the wellbeing of mom and baby.
