Welcome to St. Bonaventure CYO. Here you will find information for all three sports that are available through our program. We offer Basketball, Cross Country and Track & Field for all students in our Parish from grades 2nd-8th. For more information about the CYO league, our church, or the Diocese, please use the links. All information about the respective sports will be found in their individual section.  

In the Catholic Youth Organization (CYO) program, all children play against others at their own skill level. CYO is a local parish based group, emphasizing the teachings of Christ while instilling the joy of sport into our athletes. The athletic programs are an important youth ministry at the church. St. Bonaventure does not emphasize “winning at all costs” nor do we endorse non-becoming behavior. As representative of our parish community, we instill values of sportsmanship, fair play, both team and individual growth with Christian values. At the end of the season, the children are better athletes and more importantly better community citizens. We are also reliant on adult volunteers to help our program run. What better way to it to teach the sport you love and spread the joy of God to our children. If you would like to help us in any way or have any questions, please contact your Sport specific Athletic Director.

Thank you and Go Bulldogs!
