What Customers Say

I've been a gymnastics mom now for over 10 years, and this club wins, hands down. Most clubs focus only on physical training. Flex develops gymnasts holistically. They work on character, sportsmanship, and determination.

Cassie, the owner, and head coach spent her life as a competitive gymnast and understands the importance of mental grit in gymnastics. This is the first club that we've had emphasize this, and it's critical for young athletes.

Beyond that, the facility is new and clean, the coaching staff is warm and personable, and everyone is treated like family.

Elysha Gellerman

Coach Cassie along with all the other great coaches is amazing! The new facility is just unbelievable for the population of our area. The entire Flex staff cares about everyone one of these kids and they employ many of their own gymnasts!

Johnathan Archibald

We went there for a birthday party today and the facility is great! The staff was amazing with all of the kids (including mine, who was very shy and was a little timid to participate). My niece takes classes here and absolutely loves it. I may even sign my son up for classes in the future. Great place, and I highly recommend it.
