About Virginia Mason

The Virginia Mason Founders

Established in 1920, Virginia Mason began as an 80-bed hospital with six physician offices. It was named after the daughters of James Tate Mason, MD, and John M. Blackford, MD, who co-founded the clinic with radiologist Maurice Dwyer, MD. The founders' vision was to provide a single place where patients could receive comprehensive medical care, a "one-stop shopping" place for virtually any medical problem or need. The adjacent photograph features the original staff of physician partners.
