Gianna O’Hara, M.D.

“A big part of my job is listening. I want to learn as much as I can about my patients’ medical history as well as their daily life, because it helps me provide the exact care they need when they need it.”

Dr. O’Hara became a doctor to help older adults receive the high-quality, patient-centered care they deserve and the personalized help they need as managing their health care needs becomes more complex.
Specializing in both Internal and Geriatric Medicine, Dr. O’Hara supports patients from adulthood and middle age through their senior years.

Dr. O’Hara has always valued working with older adults and understands how important it is to help them navigate the medical system. She collaborates with her patients and their families, so they feel secure in knowing their medical decisions are good for them both physically and mentally.
In her free time, Dr. O’Hara enjoys spending time with friends and family, traveling, and playing bridge.
