Saint William Catholic Church has been serving the needs of Catholics in Marshall County from our downtown Guntersville, Alabama location since 1949. The early pre-parish organization was a mission outreach from nearby Saint James Parish of Gadsden. In 1959, the Diocese of Birmingham created Saint William Parish, and a sanctuary was erected on the present site in the center of Guntersville. An expansion project, The Foley Center, dedicated in May of 2018 includes a parish center, classrooms, commercial kitchen, and much-needed storage.
