Located on over an acre and a half immediately adjacent to the reservoir in Seattle’s Maple Leaf neighborhood, the Waldo Hospital stands as a testament to the advancement and acceptance of the practice of osteopathic medicine.  Having practiced for over a decade as an osteopath in Seattle, Dr. William E. Waldo sought to establish a hospital dedicated wholly to administering and treating patients according to the tenets of osteopathy.  Designed by Seattle architect Paul Richardson and completed in 1924, the hospital was expanded in 1959 when the architectural firm of NBBJ designed an International Style wing at the northern end of the building to increase patient capacity.  Dr. Waldo, a well-known figure locally, served as the president of the American Osteopathic Association from 1920-1922, working hard in this role to raise awareness of osteopathy as a medical field.  For his efforts, in 1948 Waldo received the AOA’s Distinguished Service Certificate, the organization’s highest national honor.
