A small round church, known as St. Hugh of Lincoln, was built in 1960, on the site that includes the current sanctuary of St. Thomas of Canterbury.

St. Thomas the Apostle (Hales Corners) and St. Hugh of Lincoln (Greendale) voted to merge parishes and form St. Thomas of Canterbury Episcopal Church. Parishioners from St. Thomas the Apostle moved to the St. Hugh of Lincoln site. The new parish, St. Thomas of Canterbury was recognized by the Diocese of Milwaukee in 1974.

Commencing in 1976, the original St. Hugh Church (the round part of our parish church building) was expanded. The construction was completed in 1977.
