About

Dr. Kent Zieser, DO, is the founder and sole physician of Exactus Physicians, a Direct Primary Care (DPC) practice in McKinney, Texas, launched in August 2016. After graduating summa cum laude from Kansas City University of Medicine and Biosciences College of Osteopathic Medicine in 2001 and completing his residency in Internal Medicine at Mount Sinai Medical Center in Miami Beach, Florida, Dr. Zieser spent years practicing traditional insurance‑based medicine. He observed the growing burden of insurance paperwork, limited patient interaction, and rising costs, which led him to transition to the DPC model.

At Exactus Physicians, Dr. Zieser offers patients a transparent, affordable monthly membership that eliminates hidden copays and insurance hurdles. Members receive same‑day or next‑day appointments, extended visit times ranging from 30 minutes to over an hour, and 24/7 direct access via phone, text, email, or video chat. By negotiating lower prices for labs and imaging—often up to 90% off retail rates—he provides high‑quality care while keeping out‑of‑pocket costs low. His philosophy centers on building meaningful, long‑term relationships with patients, allowing him to focus on preventive health and chronic disease management without the constraints of insurance reimbursement.
