In 1956, volunteer workers conducted a door-to-door campaign to raise funds to start St. Columbanus School, aided by appeals and earnest work on the part of the clergy. Initially, the campaign goal was set for $100,000. Ground-breaking ceremonies in December, 1956 were attended by about 300 people. the design called for eight classrooms, a kindergarten, a principal's office, a nurses room, a kitchen, storage facilities and the bookstore. To provide more ample facilities for Masses and other religious services, an all purpose auditorium was included in the plans. It was to seat 400 and include a sacristy, confessionals, and a stage. Space at the rear of the school was available for parking and a play area. The school actually cost $385,000.
St. Columbanus School was formally blessed and dedicated by his eminence Francis Cardinal Spellman on June 14, 1958.
