The parish was founded on the Feast of the Assumption of the Blessed Virgin Mary on August 15th, 1958. The original membership was composed of 400 German, Polish, and Italian families who gathered for the first parish Mass on August 17th in the Black Junior High Middle School's Auditorium. At the time, Pius XII was our Holy Father, the Most Reverend Wendelin J. Nold was our Bishop, and Monsignor Victor A. DiPrimeo, our Pastor. The congregation continued to meet in the Public school until a temporary church (our present Auditorium) was built on the ten-acre tract of horse pasture with a home (our present Rectory) previously purchased by the Diocese in 1952.
The first portion of our school was built in 1960. The construction of the first "permanent" church (which is now the Gym) and the school's junior high portion began in 1964 and was completed on January 10th, 1965. St. Ambrose church is one of the first churches in the Archdiocese designed to incorporate the new liturgical directives of Vatican Council II. The architects were Maurice and Charles Sullivan's, a well-known father and son team, with Robert Rambusch as their Liturgical Consultant.
The present 1,000 seat tabernacle, complete with offices, meeting rooms, and chapel, was designed by Chris DiStefano in 1995. On December 7th, 1995, it was dedicated to the feast of St. Ambrose by Bishop Joseph Fiorenza. Today, it continues to serve as the center of our faith community.
