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 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.

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. 

It is an honor to have patients place their trust in my hands. I strive to provide excellent care throughout a patient’s entire hospital stay, be it in the ED, OR, ICU or ward. Outside of work I enjoy spending as much time as possible outside with my family and friends.

My treatment focus is to ensure that each and every patient receives the best care and that their care plan is tailored to meet their individual needs and diagnosis. 

I believe that working with hematology and oncology patients is a calling and it is truly an honor to be a part of each patient’s care. It is extremely important that every patient have a treatment plan that fits their diagnosis and needs, and that this plan is communicated clearly with all members of the treatment team.

Outside of work, I enjoy reading, hiking, and walking the beach.

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.

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.

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.

My mission is to provide an accurate diagnosis in patient's with complicated presentations and complex disease states.

I am drawn to Hospital Medicine for the acute care problem solving. I believe that the patient's "story" should be accurately presented and the diagnosis should "fit" the presentation. If it doesn't, the work up continues to reveal the missing piece of the puzzle. Communicating the plan of care and expectations re:hospital course allow for a more positive experience during an otherwise difficult time. Outside of work I enjoy spending time near the water in the Ocean State and attending car shows.
