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.

Being a physician is an honor and a privilege I have enjoyed since graduating from The Johns Hopkins University School of Medicine in 1979.  As my patients know I am interested in your life, your passions and the Orthopaedic issues that frustrate you and how I might be of assistance to you.  Surgery is not always a solution.

I take care of newborn infants and their great grandmothers.  In an era of sub-specialization, I am the "silver haired" General Orthopaedist but have maintained my surgical skills and remain confident in my abilities.  I have been fortunate to have treated multiple generations of my friends and neighbors here on the South Shore and work in a hospital committed to clinical excellence and compassionate care.

I partner with women to provide education, resources and choices regarding their bodies, healthy pregnancy, labor and birth. It is a privilege to care for women and families and to be present at their birth. Each labor and birth are unique. Even after 33 years as a midwife, I am amazed at the beauty of birth and the strength of women.

I started the first midwifery practice at South Shore Health in 1987 and have enjoyed being director and now co-director of the midwifery group and watching our program grow over the years. Outside of work, I love spending time with my husband and children. I also love running my dog on the beach, paddleboarding and gardening.
 

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.

I graduated from Tufts University and received my medical degree from Albany Medical College in Albany, NY. I completed my surgical and urological residencies at Massachusetts General Hospital. I am certified by the American Board of Urology and I strive to provide the highest quality patient care in a warm compassionate environment.

It has been my privilege to practice medicine and to have made a difference in the lives of my patients over the past 21 years. I enjoy the challenges of practicing internal medicine in a hospital setting and working as part of a team with our excellent hospitalist providers, consultants, nursing and ancillary staff. I served as Medical Director of the Hospitalist Department from 2009-2015 and am proud to say that we have an amazing program with dedicated clinicians who genuinely enjoy the care of hospitalized patients and are committed to excellence in their every day work. I enjoy giving back by participating in the Pan Mass Challenge which raises critical funds for cancer research and the Multiple Sclerosis cycling events. I enjoy boating, hiking and camping, and long distance bicycling and, most importantly, spending time with my family.

I enjoy getting to work with patients in the inpatient hospital setting. As a hospitalist, I am able to work collaboratively not only with the hospitalist team itself, but also with specialists, nurses, case managers and all of the hospital staff. I appreciate being able to build relationships with patients as well. I enjoy the variety and challenges that come with working as a hospitalist. Outside of work, I enjoy spending time with family and friends and I am a fan of the Patriots, the Celtics and U.S. Soccer.

My goal is to work collaboratively with patients and their families as well as the entire care team to support critically ill patients. Clinical care and working with the entire medical team to support patients and their families are my primary passions. I am also involved in ongoing research using imaging studies to better diagnose, monitor and understand lung disease and critical illness. Outside of work, I am an avid runner and sailor, and love spending time with my family.

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.
