Why parents choose us

Skills for the gym. Character for everywhere else.

Our goal is to help kids, parents and team members be confident, courageous and compassionate.

Star charts that show progress

Every student tracks skills on a star chart, and gymnastics students move through six levels. You always know what they’re working on next.

A character trait every month

Perseverance in January, courage in February, responsibility in October. Coaches build each one into warm-ups.

A trained, screened team

First aid and CPR certification, background checks, safety certifications and abuse-prevention training for every team member.

Whole-child coaching

We teach the cartwheel and the confidence behind it, with a child-development approach in every class.
