About
At Harper Health, nine board-certified physicians deliver primary and preventive care across five locations in Illinois and Florida. Dr. William Harper founded the practice in August 2016 with 49 patients at a single downtown Chicago office. It has since grown to serve over 1,000 patients across Chicago's Mag Mile, Glenview, Hinsdale, Naples, and Sarasota.
This is the Naples Florida Location, led by Dr. Karen Larson MD.
Each physician carries a panel far smaller than the typical primary care doctor's 2,500-plus patients. That scale allows for 60-minute appointments, same-day availability, and 24/7 physician access by phone, email, or text. The practice's comprehensive three-hour annual physical draws on the same diagnostic depth found at leading academic medical centers. Each suite houses advanced technology including VO2 Max testing, DEXA body composition analysis, resting metabolic rate testing, AI-powered skin cancer screening, and cardiac monitoring. Harper Health partners with Cleerly for AI-based heart disease assessment and Galleri for multi-cancer early detection blood testing. The Florida locations focus on adults 45 and older, while the Illinois offices serve a broad adult population seeking thorough, relationship-driven primary care.
