My mission is to provide the best primary care for my patients to prevent disease. This includes regular follow up of chronic conditions and keeping patients up to date with routine screenings.

It is a privilege to provide primary care and establish long-term relationships with my patients. I believe that everyone's medical care should be individually tailored, and communication is key to providing excellent care. Outside of work, I love to spend time with family and friends. My hobbies include skiing, quilting and cooking. 

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. 

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.
