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.

My mission is to provide unbiased care to all individuals I encounter in my practice.

It gives me great pleasure to care for individuals in what may be some of the happiest and most vulnerable moments of their lives. I am passionate about getting to know patients and their families as we create partnerships to help them navigate their pregnancy and birth journey. It is my goal to help empower patients to make informed decisions about their pregnancy, health, and birth by providing them with knowledge and guidance.

Outside of work, I love spending time with my husband and children. My hobbies include refinishing furniture and woodworking.

It is an honor to have patients place their trust in my hands. I strive to provide excellent care throughout a patient’s entire hospital stay, be it in the ED, OR, ICU or ward. Outside of work I enjoy spending as much time as possible outside with my family and friends.

My career started in the US Army and it was a privilege to serve and care for women in the military and their family members while training at Walter Reed Army Medical Center and then stationed overseas in Germany for 4 years. I returned to the South Shore area since this is home and have been been fortunate to raise my family and to practice here since 2002. I am so grateful to have the opportunity to care for the women in our community. Although I transitioned to a more administrative role, I continue to practice obstetrics and gynecology here in the hospital and will continue to strive to offer the best care to patients through open communication and strong relationships.

My goal is to use my experience and training to provide personalized OB/GYN care to women to achieve healthy pregnancies and lifestyles.

I knew at the age of 5 that I wanted to be a doctor. All of my life choices have led me here. I could never see myself in any other career. It is a privilege to support and guide my patients through their hardest times, while also experiencing the joy of their happiest times. I love to tailor their medical care to them as individuals, focused on their needs and lifestyles to achieve the best outcomes. Personally, I enjoy spending tune with my family and friends, entertaining and traveling.

My mission is to provide every patient on the acute care surgery and trauma surgery services with the highest quality of care inside and outside of the operating room.

I was raised in Southern California and moved to Boston to complete my undergraduate degree in mathematics at MIT.  After completing general surgery residency in Chicago, I moved back to Boston to complete fellowships in Surgical Critical Care and Acute Care Surgery at the Brigham. I love the outdoors and spend my free time snowboarding and hiking throughout the northeast with my friends and family.

My goal is to help empower women and families and encourage them to be active participants in their care. 

I became familiar with midwifery care 20 years ago when I gave birth to my daughter with a group of amazing midwives. I was an experienced Labor and Delivery nurse at the time but, after my experience with the midwives, I knew that becoming a midwife was my true calling. I find every birth that I attend to be unique and special in its own way. I strive to help women achieve the labor and birth they desire. Everyone is different, and I enjoy getting to know families and helping them navigate this very pivotal time in their lives. In my free time, I enjoy hiking, paddleboarding, and crocheting.
