Hope Reformed Baptist Church was founded in 1996 by a group of families interested in having a distinctively Reformed Baptist church in Suffolk County, NY. Grace Reformed Baptist Church of Merrick, NY offered their oversight and assistance in planting the new church. The first service was held in Amityville on Father's Day, June 16, 1996 while the first facilities were being prepared on Potion road in Farmingville. The first service in the new facility was held on August 18, 1996 and the church remained there until it moved to the present facility in Medford on September 5, 2004.
Hope joined of the Association of Reformed Baptist Churches of America (ARBCA) in 1997 and continues to be a member in good standing.
