As a doctor at Brigham and Women's Harbor Medical Associates, I work to maintain our commitment to delivering prompt, expert and compassionate care.

My mission is to provide the very best clinical care to my patients- both in prenatal genetics and obstetrics. 

My mission is to provide compassionate care to all patients regardless of their background or socioeconomic status.

I have been passionate about health and wellbeing since I studied nutrition and dietetics in college. I believe in preventative medicine and embody a holistic approach to my care. I listen to my patients and allow them the space to make informed medical decisions about their own care. Outside of the workplace, I enjoy traveling, cooking and spending time with my yellow lab, Lily.

My mission is to help women get to the root cause of their symptoms and lead an optimal and healthy life.

I am passionate about working with patients to help them live their optimal life. I have gone back to further my education in integrative and functional medicine so that I may have more tools in my toolbox to do so. Outside of work I spend time enhancing my own health journey and being with 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.

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.
