In 1988, a group of young people that were attending a Bible study in Mililani decided to start a church in the community. At that time, Pastor Jeff MacKay was the youth pastor at Hope Chapel Kaneohe. This group of High School students asked him to be their pastor and he gladly accepted the position and Hope Chapel Mililani was born. In October of that same year, they began holding services on Sunday evenings in the cafeteria at Kipapa Elementary School. The church was rapidly growing from these thirty people. After only three weeks, a Sunday morning service was added.
For the first four years, the church was able to meet at Kipapa Elementary School for both the morning and evening services. However, this location eventually became unavailable. Since then, the church has met at variety of locations such as, Recreation Centers, other schools and the YMCA in Mililani.
