Dr. John A. Fagan, MD

Dr. Fagan offers a different approach to primary care with conveniences like same/next-day appointments that start on time and a focus on preventive medicine. His MDVIP-affiliated practice is open to new patients, including Medicare and commercially insured, in Rancho Cucamonga. Dr. Fagan sees fewer patients, which means he has more time to offer. Similar to concierge medicine physicians, Dr. Fagan is available 24/7 by phone. His practice offers the MDVIP Wellness Program, which includes advanced health screenings and diagnostic tests that have been shown to help detect issues earlier.
