Nairobi Adventist Hospital (NAH) is a Seventh-day Adventist (SDA) church-established and owned Hospital. It is a tertiary (level 4) hospital located in Nyari west area in Westlands sub-county, Nairobi County, Kenya. According to the SDA ranks, the Hospital is within the Central Kenya Conference of SDA Church (CKC) within the East Kenya Union Conference(EKUC) of the East-Central Africa Division (ECD). The facility began as a dispensary opened by missionaries in the year 1940 to provide basic health care to the surrounding community who were suffering from a whole lot of tropical diseases. The dispensary was closed down in 1955 by the colonial government over accusations of providing care to the anti-colonial Mau Mau fighters. It was, however, re-opened in January 1988 and continued to function as a dispensary, serving the surrounding community.
