This place is nothing short of incredible. Our kids have been going here for 3 years and each year the progress in their confidence, attitude and physical strength is incredible. The coaches and ownership are positive, uplifting, and wonderful. I cannot say enough positive things about Coach Jen and Coach Sean. If you are looking for a ninja gym, please do not look elsewhere. Walking in here gives me energy as a parent just hearing the positive, uplifting and amazing people here. Keep it up team. You are impacting every kid here and making the world amazing.

I cannot say enough positive things about this gym. The coaches truly care about the kids, and genuinely get to know them as both athletes and individuals. The atmosphere is positive and encouraging. I’ve been complimented on how my kids encourage others at the playground, and I can honestly say that they are passing along the spirit that they see demonstrated every class at Ninjas United. So grateful to be a part of this community.

We did not have a great experience here unfortunately. My 4 year old loved his first class and was excited to go back, but after he was singled out and targeted by one of the coaches he was really questioning himself. My son had only gone to the gym once before. The coach put him on a 5 second timer to get over the obstacles and to move off the mats. I'll remind you.. he is only 4 and has never done this before. The coach also thought it appropriate to put my child in a timeout when he didn't move off the mat fast enough for him. Coaches should be there to build up kids, not tear them down. I will never recommend this place to anyone.

Went here for a Birthday party the kids really enjoyed this place. Travis is really nice and surprisingly super fantastic with the kids, explaining how to maneuver the obstacles and with helping make sure the kids have fun. There was another coach who also was really good with the kids as well. I would recommend this place for your next party especially for boys but girls too because my daughter really enjoyed herself.

By far, one of the coolest places to take athletic kiddos! My daughter is a monkey and no playground is tough enough for her to tackle. The class we took was so awesome. They offer free play and then group the kids together to do obstacle courses. They are so encouraging and positive towards athletes of all ages and abilities. It's not about what you can't do, but what you can. They push just enough to get kiddos to keep trying, but never in a way that made my shy kiddo feel nervous or introverted. She was so proud when she accomplished things she didn't think she could do. It was a very proud and exciting day for mom!
