★★★★★NicoleAlthough it’s smaller than the Chesterfield location, we much rather prefer the atmosphere of the O’Fallon location! It felt much more personable, and the class size was not overwhelming for our children. The coaches are great at interacting with children. Very professional, and everyone really enjoyed themselves! We can’t wait for our next class! Bonus points for how clean it is as well!!
★★★★★LaToya CThis gym is so much fun. The coaches (Triple As) are energetic and give the athletes great feedback. They really do build confidence!
★★★★★Jamie BurgerMy daughter attended a birthday party here, and it was great. They did a good job engaging the kids and entertaining them and didn’t just have them run loose in the gym for an hour. The staff were really sweet with the kids, and super helpful during the food and cake portion of the party. It was obvious they cared about making it a good experience for everyone, and it was.
★★★★★Sara WiedmanMy 12 yr old son has been attending the parkour class for several months and absolutely loves working with Coach Aiden. We looked around for a while for the perfect class for him and this is it. This is the perfect class for boys who just want to flip around and have fun.
★★★★★Brittney ZwillingMy daughter Chloe loves her coaches and classmates on Thursdays at the O’Fallon location!!!! She is already learning so much for being only 3 and beginning gymnastics!
