This place is not a place for a birthday party. The party person was not made for doing a party with kids. I didn't even get a party room when I arrived.i had to wait an extra 30 mins before I even got a party room. And then we were in a party room for 10 mins for cupcakes and then had to find something to do since they were not allowed back on to the floor. For the amount of money this party cost it did not add up to what we got. I will never have a birthday party at this place again . How do you charge $345 for a party and not get the gym to yourself..( like I was told I would) and then not even have a party room when you first arrive. I wish I would of read reviews. I just wasted my son's birthday party at this place...

By far the best sport I have ever put my kids in. They have learned so much from these classes. They are in little ninjas and have a blast every week.

This place is great for anyone interested in the ninja sport. Our family started as beginners here and after years now we have found a sport and gym that the whole family loves. The staff are ALWAYS great and upbeat and keep up the positive energy whether during practice, open gym, and certainly birthday parties—which are also a blast here and well attended by invitees. I highly recommend this ninja gym.

What a great place. They’ve thought of everything to create a truly fun, creative, and challenging ninja gym for people of all ages, from toddlers to the more seasoned ninja athletes. The welcoming, nice staff are the best part. They LOVE the kids and do such a great job coaching and making them feel cared. Can’t say enough great things about Ultimate Ninjas Chesterfield. Thank you for being such a great place for my son!

The owner is engaged and awesome, just recently attended a homeschool kids event and she had a really well put together marketing table, held a raffle, and the kids had a blast! Great place to wear out your kids.

I love this place and so do ALL 4 of my kids. Management is good, classes are great and the set up changes often. It is a great place for functional strength and fun!

We visited with the kids for a birthday party. They love it!! The facility is clean and well maintained. The staff gave very clear instructions to all of the kids and watched over them during the entire party. They were very professional and made sure all the kids had fun.

Love this place. Lots to do and very cool. Can’t wait to come back for homeschool groups.

A completely frustrating experience from a competition standpoint. Nothing ran on time, obstacle changes were painfully slow, and there was zero consistency throughout the event. We’ve never encountered a competition this disorganized before.

This place is amazing! Our 4 year old daughter is in Little Ninjas. Idk how the mom coaches do it with all those littles but MAN they do! It takes a special kind of person to do what they do. I am so grateful!
