Meet Michael

I have been a Family Medicine Physician in the Lima area for many years. I attended medical school in Chicago and completed a Family Medicine residency in Columbus. I currently reside in Delphos with my wife and four children. I consider it a privilege to practice medicine in Lima and am honored to serve our local community.
