What Parents Are Saying!

This place is awesome. Trent, the owner is super friendly and helpful. He inspired our boys to try some really exciting challenges. They have a brand new, clean space with rings, climbing walls, swings, ropes, ladders, balance beams, and more! They also have a huge viewing gallery for parents to take photos and videos. Great spot. Highly recommend!

Andrew David Greer

What an amazing place, we’re so lucky to have this in our community! My daughter had her first class last night and got a lot of one-on-one training since class sizes are small. It’s a clean facility with many guided activities for kids! They even taught my daughter how to fall without hurting herself - showing her it’s ok, and expected, that she will fall but empowered her not to be afraid.After an hour class she didn’t want to leave and didn’t stop talking about it the rest of the evening!If you’re on the fence about this place, just book the class!

Whitney Hill

USA Ninja Challenge is amazing! We are so happy they are in our community. The owner is great and the gym is clean with a ton of awesome obstacles. Our son is a huge fan of American Ninja Warrior and can't wait to keep practicing his skills at USA Ninja Challenge!
