Our Mission... Founded in 1929 and true to the tradition of the School Sisters of St. Francis, Our Lady of Perpetual Help School is the largest Catholic elementary school in the Chicago Archdiocese. It is open to all OLPH Parish families who want to provide their children with every opportunity to identify, express, and celebrate a growing Christian faith as they acquire a foundation of knowledge and discipline, leading to the service of others in the spirit of Jesus Christ.
