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.

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.

I consider myself lucky to do something that I love. Children and teens are great at reminding adults about the little joys of life while also presenting us with various medical and behavioral challenges. I enjoy navigating these challenges with each family to find the right approach for their child. Outside of work, I love spending time with my husband and three (lovable and challenging) children. I enjoy running with my dog, biking, swimming, skiing, and occasionally a good day of yard work. 

I earned my Bachelor of Science degree from Boston College and my medical degree from Loyola University in Chicago. Upon graduation from Loyola, I returned to my native Long Island to complete my residency in pediatrics at SUNY Stony Brook. Following an additional year as Chief Resident, I returned to Massachusetts to settle. Professionally, I cherish the privilege of establishing long-term relationships with my patients' families and playing a small role in assisting a child to blossom into a happy, healthy, well-adjusted adult. In my spare time, I enjoy kayaking, practicing yoga, going to the beach, and spending time with my husband and five children.
 

I grew up on the South Shore and attended Holy Cross for college where my concentration was pre-medical sciences and sleep research. During summers in college I worked as an EMT and following college I worked in a collaborative Brigham and Women’s Hospital/Harvard Medical School lab studying allergy and asthma. While at the University of Massachusetts Medical School and Lahey Clinic my focus was on primary care internal medicine. In 2006 I was the recipient of the “Patient Care Award” which is Lahey Clinic’s highest physician honor. I joined South Shore Medical Center in 2006.

Prior to joining Cohasset Pediatrics I practiced pediatrics south of Boston for nine years and was Chief of Pediatrics for four years within that practice.  

I received my undergraduate degree in Drama from New York University’s Tisch School of Arts.  Working as an actress afforded me the opportunity to travel professionally and experience life as a performing artist in New York City, Los Angeles and London. While working in show business was certainly exciting, I found my true calling working as a physician partnering with parents to help provide the best medical care for their children.

When not at work, I love spending time with my husband and two children and enjoy singing when I get the chance.
