The St. John's Bazaar is held the last Friday of October each year. The event, sponsored by CHI St. Vincent and local businesses, begins with an All-School Mass, a bake sale, a virtual silent auction lunch prepared by the Men of Mary from St. Mary of the Springs Catholic Church, a spaghetti dinner, prepared by the Knights of Columbus, and a live auction. Throughout the day, the students enjoy carnival games and inflatables. The Bazaar is the major fundraising event for the school and typically raises $80,000 - $90,000.
