CHAK's history dates back to the 1930s when it was established as a Hospitals' Committee of the National Council of Churches of Kenya (NCCK). In 1946 it attained autonomous legal registration under the name of the Protestant Churches Medical Association (PCMA). Its mandate was limited to distribution of Government grants to Protestant Churches' health facilities.
In 1982 the Association changed its name to Christian Health Association of Kenya (CHAK) and took on the broader mandate of facilitating the role of the Church in health care and the healing ministry.
CHAK is an organization that is committed to growth through continuous learning. The programmes of the organization are guided by the vision and mission which are articulated in strategic plans that cover a period of six years. The Strategic plans are aligned to the National Health Sector Strategic Plan and Health Policy Framework and are responsive to the environmental changes. The strategy is implemented through three-year programmes which undergo monitoring and end-term evaluation that generate lessons to inform programmes improvement.
CHAK engages in advocacy for health policy, recognition, involvement and resources to scale up quality health services. The organization promotes networking for sharing lessons and experiences within Kenya and with other Christian Health Associations in Africa and also internationally.
Resource mobilization is done through building partnerships, project proposal development and advocacy. CHAK welcomes partnerships and funding support from any potential partner to facilitate health systems strengthening and scale up health service delivery in any part of Kenya.
