History:
Ko'olau Baptist Church was establish in 1965 when a young missionary couple from Baptist International Missions Incorporated, Pastor and Mrs. Max Helton, arrived in Hawaii. With a small nucleus of believers they organized the Ko'olau Baptist Church. Originally they met at Heeia Elementary School before later moving to the cafeteria at King Intermediate School. Later, approximately 2.5 acres of an old banana patch were purchased in Kaneohe and the church built a sanctuary in on the location in 1967.

Under the leadership of Rev. James Warren (1972- 1976) Ko'olau Baptist Church gave birth to a new ministry by founding Windward Christian School in 1974. Approximately 30 students met in a small A-framed annex building, an old real estate office that was moved onto the Ko'olau Baptist Church property.

Under the leadership of Rev. David Marcum (1976-1980), the church and school began to grow in numbers and more room was needed. As a result, in 1978, the back of the church sanctuary was expanded for use as Sunday school classrooms as well as Monday - Friday school classes. Shortly thereafter, the name "Windward Christian School" was changed to Ko'olau Baptist Academy. This change, in name, more accurately aligned the school ministry under the Pastoral leadership and direction of the local church body (as embarked upon in 1974) of Ko'olau Baptist Church.
