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 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.

It is truly an honor to participate in the care and lives of my patients. My passion is driven by the bonds I build with my patients over the course of their lives and the enjoyment and satisfaction I hold in treating them to be as healthy and pain free as possible. It is to the extent that I feel that  "I truly have the best job in the world."

I take great pride in the opportunity to improve patients' lives. Everyone has their own story and I do not view patients as defined by their age or conditions. I seek to work with the individual in order to help them be better. Outside of work, I enjoy golf and spending time with my family. 

I am a Magna Cum Laude graduate of Boston University, and I received my medical degree from Boston University School of Medicine. I completed his surgical and urological residencies at the Albert Einstein/Montefiore Medical Center in Bronx, NY. Upon my graduation, I joined South Shore Urology. I am certified by the American Board of Urology and I strive to provide the highest quality patient care in a compassionate environment.

I really enjoy working with the pediatric population. Kids are so energetic, willing to learn and eager to challenge themselves. The beauty of pediatric primary care is that one day is never the same, every child is so unique. There is always new knowledge to gain. Outside of work, I enjoy spending time with my family, running, swimming, and vacationing on Cape Cod. 

Dr. Devan grew up in New Hampshire and received a bachelor's degree in engineering at RPI. He earned his MD at Tufts in 2017 and completed his urology residency at Maine Medical Center in 2022. His focus is general urology and robotics. He enjoys developing a shared treatment plan with his patients. Outside of medicine, he enjoys spending time with his husband and family.
