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.

I love Dr. Armstrong; she is always extremely helpful and knowledgable. It's clear that she looks at my files before I come in and I know she has also done research after I leave to make sure she is giving me the most up-to-date recommendations. I can't praise her highly enough.

Amazing.

Dr.Armstrong always asks my opinion on my care, and answers my questions without dismissing them or making me feel silly or dumb for asking. I just love her!
