Mission Statement

The mission of Charter Oak Gymnastics is to provide a safe and caring environment in which each child knows they have value. COG strives to teach respect, confidence, self-esteem, self-discipline and work ethic to enable each child to be the best athlete and person they can be.  

Charter Oak Gymnastics is devoted to helping all participants reach their physical and mental fitness goals regardless of ability. From the very beginner student to the world competitor, it is our goal to provide the best possible gymnastics instruction to all students. We understand that success is a choice.  It is our hope that the disciplines we teach that lead to success through gymnastics will also be recognized as a lifelong benefit. This is the greatest gift we can offer our community.
