Founded in 1966, Temple Shaari Emeth originally had 50 member families, and had its facilities at two Manalapan residences. Irwin Goldenberg was the congregation’s first religious leader. The congregation established a religious school, with 23 students attending the first class which was held on February 18, 1966 at the two Manalapan homes. The U.S. Route 9 corridor in Manalapan was expanding quickly, and many Jewish families from New York City were relocating to the area. By 1967, the members of Temple Shaari Emeth needed more space for the growing congregation. In 1968, Kevork Hovnanian donated 3.5 acres of land on Craig Road in Manalapan. Construction of the new synagogue began in May 1969 and was completed in April 1970. The synagogue underwent a major renovation in 1990.

The religious school has 527 students in grades K-10, with another 16 students enrolled in the school's post-confirmation program (grades 11-12).
