In 1984, St. Ita, a mission to St. Bernadette Catholic Church in Hollywood, was established. A group of about 60 Catholics from Sunshine Ranches and the surrounding community celebrated Mass in a volunteer firehouse on Hancock Road.
As the faith community grew, Archbishop Edward McCarthy saw the need for a permanent Church in the area. With Rev. William Hennessey as founding pastor, St. Mark Parish was established in July 1985.
