Meet Diane

I joined the Mercy Heath system in 2009 and have been practicing at Fairfield Internal Medicine and Rheumatology. I provide primary care services to patients of age 16+. I feel privileged to provide care to families in the Cincinnati area for over 30 years now. I live with my husband in Liberty Township and have 2 grown children and 1 grandson. In my spare time, I enjoy classical music, decorating, flowers/plants and nature.
