Saint Hilary Athletics and CYO Sports 

Saint Hilary is a member of Catholic Youth Organization (CYO). CYO's mission is to provide an environment that promotes team spirit, hard work, good sportsmanship and fair play. This is a parish and community based athletic program that involves both our own Saint Hilary children, as well as students from the greater community. CYO strives to provide a quality experience and encourages the participation of all young people and fosters the development of Christian values in the Catholic tradition.

CYO is committed to increasing the player's understanding of the game, building character, self-esteem and discipline, developing responsibility, and adding to their enjoyment of the game. These are all lifelong traits.

Saint Hilary CYO offers volleyball in the fall, basketball in the winter and track in the spring.
