Our Three Campuses
Chicago Christian Schools offers three convenient campuses—Tinley Park (Preschool-8th), Oak Lawn (Preschool -8th), and Palos Heights (9th-12th)—rooted in the Chicago Southland. With families coming from across 200 square miles, Midway to Monee, CCS serves as a bridge from the city to the suburbs, with bus transportation available. Choose the location that’s close, convenient, and feels like home.
