Calvary Church of Orland Park, founded in 1886, is headed by senior pastor Rev. Howard Hoekstra and executive administrative pastor Rev. Ronald Ovitt. The church offers an array of classes and ministries appealing to various needs, desires, and ages. Worship services are held on Sundays at 8:20am, 9:40am, and 10:45am. Calvary offers a contemporary, blended and traditional service to appeal to the congregation's differing needs.

Due to increasing size the church is moving their facility to 159^th Street and 104^th Avenue. Until construction is finished, worshipping will be held at Marcus Theaters. The church's office location has been moved to 19065 Hickory Creek Dr., Mokena, IL.
