Quaker Medical Associates is dedicated to giving you and your family the highest quality care.  Our physicians are dual board certified in both internal medicine and pediatrics, and use the highest levels of evidence based medicine to care for patients of all ages.

In 1989, Francis Mezzadri, MD, cofounded the practice that grew into Quaker Medical Associates, with a vision to create a practice that would provide the highest quality primary care to WNY families.  Over the years, other talented physicians joined the practice and added to its reputation of quality and excellence.  Quaker Medical’s physician owners continue to value evidence based medical care of you, their patient, over profits, and have chosen to remain an independent physicians’ practice rather than be acquired by a larger health care organization.
