Review from Google · view on GoogleMy son has been coming here every week since he was 3½ years old, and he still looks forward to every class. He’s now 5, and his love for it has only continued to grow. The staff are always kind, welcoming, and make every visit a great experience. They’re also incredibly understanding and flexible if we ever need to reschedule a missed class. We’re so grateful for such a positive environment and everything they do. I highly recommend this place to any family :)

Review from Google · view on GoogleThis 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...

Review from Google · view on GoogleSigned my 4 year old up for a half day camp during spring break. Today was the first day of that camp and the experience was horrible. My husband stayed an hour after the start time and these were his observations: it started 30 minutes late, there was no structured programming, most kids were huddled in a back room watching TV on a tiny screen, there were kids of all ages there at the same time and had freedom to do whatever they wanted. My mom picked up my daughter an hour early from the scheduled end time because we didn’t want her to stay long in that environment and she confirmed it was still the same non-structured situation when she got there. It’s essentially just babysitting and the Wild West. So disappointing and baffling because this place seems to have good reviews. My daughter cried uncontrollably on the way home so it clearly wasn’t a good experience.

Review from Google · view on GoogleBy 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.
