We had a birthday party for our 5 year old and it was perfect! The owners were helpful and also easy going. You bring the decorations and staff is more than happy to help you set up and give you the space and flexibility. The kids had so much fun in the gym. It was a good mix of free play and structured challenged. It was well organized. The space is very clean and it is private. Parking is easy. Amy was such a warm and kind energy to have help support the party. Absolutely...

Ninja challenge is the perfect addition to any families physical fitness programing. This one of a kind class offers 100% hands on learning. What kids like best is participation! There are no sidelines at ninja! They keep the kids moving in fun ways each week that progress them in all areas. They jump , swing, hang, climb, run and also learn about being a great team mate. The confidence these kids gain is invaluable! Sign up, give it a try. Your kids will love...

We've been super happy with having our son in a weekly ninja class at USA Ninja Challenge! The growth that we've seen in his confidence and abilities on the obstacles is wonderful. Our son enjoys his classes so much that he had his most recent birthday party at here and all of the kids had a blast! The coaches did a great job and kept all of the kids engaged. Highly recommend USA Ninja Challenge for your child if you're looking for something...
