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 diagnose, educate and treat patients about their orthopedic conditions.

Whether the time we spend together is short or long term, I strive to ensure all patients understand the nature of their conditions, and I look forward to see their progression and improvement throughout our journey together. I was born and raised in Weymouth, because of this, I am excited and honored to serve the community I grew up in.

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.

I take great pride in the opportunity to improve patients' lives. Everyone has their own story and I do not view patients as defined by their age or conditions. I seek to work with the individual in order to help them be better. Outside of work, I enjoy golf and spending time with my family. 

My goal as a physician is to help patients learn about the importance of following preventative measurements and living a well-balanced life to tackle many diseases before they become debilitating illnesses.

I am excited to be part of the South Shore Hospital Medicine team. I believe patient education and communication are the key components to provide the best possible care to all my patients. My training has helped me master the skills to provide evidence-based, culturally competent, and patient centered care to all my patients. It is my honor to be able to provide you the needed medical care while you are admitted to the South Shore Hospital.

Outside of work, I love hiking, painting, and exploring different places.

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.

I look forward to helping patients and members of our community navigate unexpected and stressful health events with extra attention to the patient and their most immediate loved ones, family, and friends. 

I look forward to providing care and service to the community that my wife and I have called home since 2010. We have two beautiful children who lovingly occupy the majority of our free time when not providing healthcare at South Shore Health. 

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 have been a nurse practitioner since 2005 and truly love coming to work every day.  I feel so privileged to help kids when they aren't feeling well. Outside of work, I am a Mom to four kids. I feel like that helps my practice so much, I can totally relate to both the joy and stress of being a parent. I am married to a man that I have known since third grade, and we live in the town that we grew up in. I am a pretty lucky person.

My goal is to establish open communication with patients so we can work together on taking ownership of their health and wellness.

I enjoy the meaningful relationships I have built and the inspiration I draw from patients every day in clinic. A healthy dialogue is an important part of the provider-patient relationship. Outside of work, I enjoy spending time with my family, writing, and staying active outdoors.
