Over 100 physicians with UBMD Physicians' Group have been selected as Western New York Top Doctors through Buffalo Spree magazine. The list was compiled through a peer-review survey of Western New York physicians in Erie and Niagara counties.


"We're incredibly proud of our physicians for their continued dedication to our patients and everyone in WNY," said Kevin Gibbons, MD, executive director of UBMD Physicians' Group.

"All of our physicians play a unique and essential role in WNY healthcare by working across health systems, providing in-patient and outpatient care, as well as leading clinical research and teaching the physicians of tomorrow through our work at the University at Buffalo."

Physicians from 14 UBMD practices across 47 specialties were named to this year's list.
