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 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. 

As an admitting hospitalist, my focus is to facilitate a smooth transition between the emergency department and the inpatient  admission. 

Waiting to be admitted to the hospital can be nerve wracking, emotional, and even scary. My goal is to ease  your transition from waiting in the ER to being admitted, explain your condition, and answer all questions you may have. Raised and educated locally, it is my pleasure to serve this wonderful community of people who call the South Shore home. In my free time, I enjoy traveling, spending time with family and friends, and exploring/discovering all that the area has to offer.   

My goal as an FNP is to create a safe and welcoming environment where patients can openly share their concerns and trust that I’ll provide the best possible care. 

I always strive to better my practice to have the opportunity to make a difference in my patients' lives. I want to be the provider that patients come to, knowing they will feel heard; and empowering them to take control of their overall wellbeing. I believe in the importance of going above and beyond for each individual patient to optimize their quality of life. Outside of work, I enjoy traveling and hiking with my wife and dog!

Treatment of disease begins with a correct diagnosis, using all of the available clinical and laboratory data available. While we do not have the same visibility to the patient as their primary care provider or surgeon, pathologists are an integral part of every patient's health care team, assuring that their physicians have accurate and timely pathology and laboratory data on which to act.  Away from the office, I'm a singer and cellist - you can find your way to my office by following the music.
