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 treatment philosophy and focus is to diagnose and treat patients ages 15 – 100 whom have a variety of breast issues including but not limited to infection, pregnancy related breast issues, genetic risk for cancer, abscesses, skin disorders, abnormal breast imaging, breast lumps, and past or current personal history of breast cancer.

I worked in New Jersey for 20 years in Internal Medicine and combined Oncology prior to relocating to Massachusetts in 2003.

Patients with vascular disease often face many challenges—medical and otherwise. Consequently, I recognize that there are many important aspects to your care.  I also appreciate that having surgery is a major life event. With all of this in mind, I will do my best to provide you with patient-centered, high quality, effective and compassionate care.

My mission is to help patients find out their disease, assist in curing it and live healthy life.

With compassionate care, I love to help people come out of their suffering. I believe that every individual is different so we should respect them and treat appropriately. Good communication is always very crucial. During my free time I love to listen music, play guitar. Also, I like meditation, yoga/ pranayam. However, most importantly I love spending time with my family.

I joined the team in 2015 coming from years of experience as a floor nurse at a Boston-based city hospital. Many elements of my floor nurse practice included disease knowledge/management and wound management.

I enjoy collaborating with my fellow practice physicians to determine the best care options for our patients. In terms of wound care, the mechanisms we use to help a patient to heal are very much individually tailored. This requires that I really know my patient and their level of activity, what they do on a daily basis and any physical or psychosocial elements which can interfere with healing. Knowing my patient's personally helps me to tailor their care and determine elements which would be most effective for healing.

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.

I aim to improve patient’s lung health and help patients and families through critical illnesses.

I work to provide excellent care in the acute and outpatient settings, in close collaboration with other specialists and staff. I am passionate about helping everyone reach their individual health goals.

It is a privilege to treat patients compassionately in our community. I strive for excellence, open communication, accessibility, and long-term relationships. Outside of work, I especially love spending time with my family, swimming, bicycling, tennis, golf, sailing, photography, and magic.

I am the Medical Director of Population Health for South Shore Health and divide my time between administration and patient care. My administrative interests include integration of care, professional development, and community centered program development. I value long-term relationships with my patients and find it a privilege to care for patients over their lifespan.
