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.

Establishing a good patient-physician relationship is crucial to help provide the best care. I believe in allowing ample time in a visit to listen to my patients' needs and thoroughly explain their diagnosis and treatment plan. Most podiatric issues can be treated with aggressive conservative therapy, although when surgical intervention is necessary, I will communicate that to the patient in a direct and concise manner. 

As a primary care clinician, I have the opportunity to develop a trusting partnership with my patients and their families to help them live a healthy lifestyle. I enjoy diagnosing and treating the various illnesses that affect patients during their lifetime, and take great pleasure in seeing them recover. It is important for me to listen carefully to my patients' concerns so we can work together to meet their individual healthcare needs.  

In my free time, I enjoy swimming, running, cycling, and skiing, in addition to spending time with my husband, adult children, and our new granddaughter.

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 strive to provide excellent care to my patients and to help them understand their conditions through education.

As a rheumatologist, my goal is to take care of my patients as individuals and to work together with them to find the most effective treatment plan. I am passionate about helping patients with rheumatologic conditions find relief with the therapies we have available today. Outside of work, I enjoy playing tennis, exploring new restaurants, and spending time with family and friends.

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.

In my career as an emergency physician, I have gotten to take care of patients in both the usual emergency department setting as well as some other unusual environment. Regardless of the location, one thing remains the same - it is about the patient and the care they need at a time of medical crisis. I spend most of my time outside of work, still engaged in medicine with a variety of emergency response organizations as well as the military.

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.

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 provide patient-centered care allowing our patients to access trustworthy and well-informed care.

My personal philosophy in life is to be kind and compassionate. My background is in adult-gerontology and neurosurgery. I aim to create patient-centered relationships where my patients feel comfortable disclosing any concerns. In addition, I aim to provide open communication. Outside of work, I enjoy volunteering at a local nursing home and a local food bank, and performing in an dance group in ballet, jazz, contemporary and hip hop. I also enjoy hiking and exploring local trails.
