I strive to build a space where patients feel safe to discuss their health concerns and engage in shared decision-making.

Prior to joining South Shore Health, I had the privilege to train at UMass Family Medicine Residency and complete an additional year of fellowship to also care for patients living with HIV/viral hepatitis at the Family Health Center of Worcester.

Outside of work, I love spending time with my family, running, gardening, and camping/hiking.

Having grown up on the South Shore, it is a pleasure to care for patients of this region. I served in the US Navy following medical school and completed my surgical training through the Navy. Following multiple military assignments, I chose to return to the area in order to serve my local community and reside closer to my family. 

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.

I'm a Senior Network Physician practicing at Dana-Farber Community Cancer Care in Weymouth. I am certified by the American Board of Internal Medicine in Hematology, Medical Oncology and Hospice and Palliative Medicine.  I received my BA from Oberlin College and my MD from Tufts University School of Medicine.  I did my training in Internal Medicine at Boston City Hospital and her Hematology-Oncology training at New England Medical Center. In my free time, I enjoy traveling, music and outdoor pursuits.

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.

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.

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.

My mission is to give the same care to my patients as I would want for my family or myself.    

I was born and raised in the Boston area.  After a long period of schooling and training across the country (New Hampshire, Ohio, California, Pennsylvania), I have been honored to return home to take good care of my people!  When not fixing retinas, I enjoy spending time outdoors with my wife and three children.   

I graduated from Colegio Nacional de San Isidro in Buenos Aires, Argentina and completed my medical degree at Buenos Aires University School of Medicine. My surgical and urological residency were spent at the Hospital Italiano in Buenos Aires. I was an attending Urologist at Hospital Roffo in Buenos Aires until I came to the United States. At that point I was a Urology Fellow working on a research project at the Children’s Hospital and Harvard Medical School in Boston. I completed my American residencies in urology and surgery at the University of Massachusetts.

I enjoy spending time with my wife and three children.

My job is ultimately about the trust that comes from a long-term relationship.  I am honored that people choose me to care for them and their extended families, and I do my best to give thoughtful and evidenced based advice.  Each of us has unique goals for our long term health, and I really enjoy giving people guidance in this realm.  I also enjoy the challenge of my work.  Each day is extremely diverse and forces me to stay continually current.  When I am not at work, I love competing in triathlon and cycling events, skiing, travel, and being outside.  I also adore being a father to my three daughters.
