The PACE model of care can be traced to the early 1970s, when the Chinatown-North Beach community of San Francisco saw the pressing needs for long-term care services by families whose elders had immigrated from Italy, China and the Philippines. William Gee, DDS, a public health dentist, headed the committee that hired Marie-Louise Ansak in 1971 to investigate solutions. Along with other community leaders, they formed a nonprofit corporation called On Lok Senior Health Services to create a community-based system of care. On Lok is Cantonese for "peaceful, happy abode."
William Gee, DDS, and two others execute articles of incorporation for the nonprofit Chinatown-North Beach Health Care Planning and Development Corporation (later renamed On Lok Senior Health Services) and retain Marie-Louise Ansak to study the feasibility of building a nursing home in the community. She finds a nursing home would be financially infeasible and culturally inappropriate. Instead, she obtains funding to train health care workers in cooperation with the University of California San Francisco. She also outlines a comprehensive system of care combining housing and all necessary medical and social services based on the British day hospital model.
