History of PACE and On Lok

Serving the elderly for over 45 years, On Lok has grown from its humble roots as an adult day health care center to a complete medical and health-related services program that is now replicated throughout the United States.

On Lok, which means “peaceful, happy abode” in Cantonese, pioneered the model of care known today as “Program of All-inclusive Care for the Elderly” or PACE, which now is a certified Medicare program and an optional Medicaid benefit in the states.

History of PACE and On Lok Lifeways

  • 1971

    On Lok was formed in 1971 in response to community concern for the older adults of San Francisco’s Chinatown, North Beach, and Polk Gulch neighborhoods. Dr. William L. Gee, a public health dentist, headed the committee that hired Marie-Louise Ansak in 1971 to investigate solutions. They, along with other community leaders, formed On Lok Senior Health Services to create a community based system of care.

  • 1973

    On Lok Senior Health Services opened one of the country’s first senior services health centers in San Francisco. Elders in these San Francisco communities received hot meals, complete health services, social services, and supervision during the daytime, while returning to their homes in the evening.

  • 1975

    On Lok added in-home support services, then primary care services and case management of acute and chronic health services.

  • 1979

    On Lok launched a Medicare-funded demonstration of our consolidated model of long-term care through On Lok Senior Health Services. An interdisciplinary team (physicians, nurses, physical and occupational therapists, social workers, dietitians, health workers, and drivers) formulated coordinated care plans and provided all medical care and senior services to the elderly in and around San Francisco.

  • 1983

    On Lok obtained waivers from Medicare and Medicaid to test a new financing method for long-term care: a form of risk-based capitation. In exchange for fixed monthly payments from Medicare and Medicaid for each enrollee, On Lok was responsible for delivering the full range of healthcare services, including hospital and nursing home care – bearing full financial risk.

  • 1986

    Congressional legislation made On Lok’s waivers permanent and authorized similar waivers for community-based organizations replicating the model. On Lok’s groundbreaking model of coordinated service delivery and innovative financing began replication under the new name, the Program of All-inclusive Care for the Elderly (PACE).

  • 1994

    On Lok completed renovation on the Larkin building, now named the Dr. William L. Gee Center, in honor of its founding Board President Dr. William L. Gee. The National PACE Association, a non-profit membership organization comprised of PACE sites providing senior services throughout San Francisco was formed.

  • 1995

    30th Street Senior Center became part of the On Lok family of complete health services under an agreement with the California Pacific Medical Center. 30th Street Senior Center provided bilingual and bicultural services to San Francisco seniors since 1979. The existing 30th Street services, including nutrition program, senior services, adult day health center, and Alzheimer’s program, continued.

  • 1996

    On Lok’s PACE program, then called On Lok Senior Health, opened two new centers, one through a partnership with the Institute on Aging and a second at the 30th Street location. On Lok now provided senior services throughout the City and County of San Francisco.

  • 1997

    In the Balanced Budget Act of 1997, PACE became a permanent provider type under Medicare and a state option under Medicaid. Thus, the undertaking that started with a few dedicated people in San Francisco had blossomed to become a nationwide movement whose continued goal is to create a better life for the frail elderly.

  • 2002

    On Lok opened its first PACE center outside San Francisco in the City of Fremont, which initially served two orders of nuns, the Sisters of the Holy Family and the Dominican Sisters of San Jose.

  • 2003

    On Lok transitioned from waivers to become a permanent PACE provider under Medicare and Medi-Cal. State legislation established PACE as a permanent Medi-Cal benefit.

  • 2006

    On Lok changed the name of its San Francisco senior services PACE program to On Lok Lifeways and adopted a new brand for its five non-profit corporations. On Lok also opened the Mission Center in San Francisco’s Excelsior District and expanded the Southern Alameda County service area to include Fremont, Newark, and Union City.

  • 2009

    On Lok opened a new PACE center to provide its complete health services in the City of San Jose to serve the Santa Clara County service area (not including Gilroy, Morgan Hill, and San Martin).

  • 2012

    On Lok opened the Peralta Center, a second PACE center in the City of Fremont, which was developed in partnership with Eden Housing and located in a commercial space with Eden’s 98-unit low-income senior housing project.

  • 2014

    Expanding its commitment to providing senior services in Santa Clara County, On Lok opened the East San Jose Center, an alternative care setting to the On Lok Lifeways San Jose Center for On Lok Lifeways PACE participants. The center had previously been an adult day health care center, which served the community for many years.

  • 2017

    On Lok converted the East San Jose Center to a PACE center by adding a clinic to this facility.

  • 2019

    On Lok expanded its existing service area in Santa Clara County to include the cities of Gilroy, Morgan Hill, and San Martin. On Lok also opened the The Harry and Jeanette Weinberg On Lok Memory Care Center, On Lok’s first PACE alternative care setting in San Francisco, providing specialized memory care services to PACE participants.

  • Today

    Over 126 PACE programs are operating in 31 states. On Lok Lifeways serves over 1,600 frail seniors in San Francisco County, Santa Clara County, and the cities of Fremont, Newark, and Union City in Alameda County. The 30th Street Senior Center now serves over 5,000 seniors per year in San Francisco.
