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.

My mission is to provide excellent care to all of those in need with compassion and empathy.

I grew up in Duxbury, MA on the South Shore and attended Colby College in Maine. I then obtained my Master of Science degree at Mercer University School of Medicine in Georgia. After securing those credentials I attended MGH Institute of Health Professions for PA school, where I graduated in 2021. I take pride in getting to know each patient, their specific medical condition and then guiding them through difficult medical pathways and stressful circumstances. I enjoy my work/life balance and love traveling, workout classes, skiing, and everything wellness.

I try to have a collaborative approach to disease management and prevention, with an eye towards the most value for the patient's dollar.

I have been lucky enough to be a family physician since 2010. Since then, I have worked to provide cost-effective and compassionate care for my patients. I'm also committed to advocacy for my patients and fellow MD's outside the office, though my role on the Massachusetts Academy of Family Physicians. I enjoy traveling, hiking, gardening, and computer gaming, when my young children allow any of them.

My mission is to provide exceptional urological care. 

I graduated from Wake Forest School of Medicine with a Master of Medical Science. As a Physician Assistant, I have been practicing Urology for over 15 years. I am a compassionate provider and focus on treatment plans that are individualized. Outside of work, I enjoy traveling, reading, and spending time with my husband and dog Murphy.

It is such an honor and privilege to be a physician.  It has been especially gratifying to devote my career to the field of Hospital Medicine, and to work at South Shore Hospital to help serve my community. 

Being hospitalized is often one of the most challenging and frustrating experiences a person can have. As a Hospitalist, what is so rewarding is that I can use my training and abilities to make such difficult times for people more compassionate and less confusing. 

Outside of the hospital, I love spending time with my wife and young son and traveling.  I also love anything to do with the outdoors and enjoy running.
