Founded in 1996 by two renowned Seattle-based physicians, Dr. Howard Maron and Dr. Scott Hall, MD² developed an entirely new conceptual model for primary care medicine, which has come to be known as Concierge Medicine. Now spanning the nation and providing patients access to the foremost medical institutions and specialists in the country, MD² is regarded as the preeminent provider of personalized medicine. This is medicine in the ideal. Only MD² physicians dedicate their practices to just 50 families. The result is an unparalleled caliber of care and service bestowed upon their patients. It is a return to personal service in which the patient-doctor relationship is at the heart of all medical decisions. Dr. Maron has said, "this is healthcare the way it should be, with zero compromises. It's about being cared for in the way you would care for your own family members."​ MD² has concierge medical practices in well-traveled cities across the U.S. and ties to all major centers of medical excellence. Current cities include New York, Morristown, Boston, Wellesley, McLean, Chicago, Dallas, Austin, Houston, Beverly Hills, Santa Monica, La Jolla, San Francisco, Menlo Park, Los Altos, Portland, Bellevue, and Seattle, with future offices opening in Denver and Nashville in 2023.
