COSC Mission Statement

Canyon Optimist Soccer Club serves our community by promoting teamwork, development, and relationships in a safe and fun environment.

About Canyon Optimist Soccer Club

Canyon Optimist Soccer Club (COSC) is an all-volunteer, non-profit organization dedicated to providing the Caldwell, Vallivue, Nampa and the surrounding Treasure Valley with a low-cost soccer program for kids. Our goal is to provide programs where kids have the opportunity to learn skills, but most importantly, to have fun playing soccer! We are always in need of volunteers, either for board duties or coaching, who have the heart to serve the community by helping make this program run smoothly and efficiently. For more information on how you can help, please contact someone on the Board or come to the next Board Meeting.
