Can't say enough about this place! The kids love it and the staff is all super friendly and helpful. Best of all, most places like this cost an arm and a leg but this one was VERY fairly priced. Will be coming back here a lot!

Wasn’t impressed. Went for a free hour program. It wasn’t a good fit for us. No attempt was made to talk us into anything or explain anything. The place appeared to be ran by young adults (kids really). The one adult I saw that looked like he may have been in charge, did not seem to wanna be there at all. We will try something else like karate. We had such high hopes for this place and it’s 4.8 rating.

My son competed here and had a great time! The competition was really well organized and moved right along. He was really excited to meet Jamie Rahn, aka Captain NBC. Jamie was great with the kids; he was patient and asked each child individually if they had any questions. The facility is really nice with lots of great obstacles. I can't wait to go back for another competition and just wish we lived closer to it so my son could train there!

If I could give this place 20 stars I would. We had a birthday party at Ultimate Ninjas today and had the BEST time! Grace and Harper were amazing! The whole staff was super helpful. They decorated and set everything up! They made sure all of the kids were engaged and having fun. They made my nephews 7th birthday super special and fun! I would recommend this venue for an event!! Thanks again for being awesome!!

Great facility for Ninja Warrior obstacles. The staff is well organized, and the facility is clean. It's a great place for kids or adults to do classes or even have parties!

Came for a birthday party. Was a good time. Only minor negative was 4 girls all got cut on the obstacles course. So there must be some little barb or something sticking out of the metal.
