Oak Tree Presbyterian Church began as a shared dream. A diverse group of individuals from the Oak Tree section of Edison yearned for an ethnically integrated community church to bring the "Good News" of Jesus Christ to the local communities of Edison and South Plainfield. Nurtured in its infancy by both the First Presbyterian Church of Metuchen and the former Marconnier Reformed Church, the new congregation began worship in September of 1963 at the Oak Tree Elementary School (presently JFK's Hartwyck) with the Rev. Dr. Chester M. Davis as the founding pastor. In 1964, a committee was formed to purchase the property on Plainfield Road. After generous financial assistance from the First Presbyterian Church of Metuchen, the Presbytery of Elizabeth and its ninety members, the property was purchased. Construction on the building began in September 1967, and was completed in the Spring of 1968.
The first service was held on Palm Sunday, April 7, 1968, with Rev. Robert Seaman as the pastor.
