About
Dr. Charles Opperman is an internal medicine physician and the founder of Simplicity Health Direct Primary Care in Centerville, Ohio. He previously practiced at a large health network, where 20-minute appointment slots defined his day. He left that role to build a practice centered on unhurried, relationship-driven care. Dr. Opperman practices strictly evidence-based medicine and takes a vocal stance against alternative and functional medicine approaches.
He is passionate about antibiotic stewardship, hypertension and diabetes management, weight loss, and insomnia. One of his guiding clinical beliefs is that stopping unnecessary medications can be just as meaningful as prescribing them. He has personally delivered medications to patients on weekends and driven to patients' homes during illness to provide hands-on support. Dr. Opperman is a devoted Dayton Flyers basketball fan and husband to Sara, who manages the practice.
