    We just held our daughter's birthday party here, and I was really impressed! Our party hosts were incredibly organized, attentive and energetic. They did a great job of explaining the rules to the kids and keeping everyone safe. They helped me set up the party room, cleaned everything up after and provided a cart for us to load items into our car easily. The kids had a great time! I highly recommend Ultimate Ninjas Academy!
    We had such a blast celebrating my son’s 6th birthday! The boys all had a blast climbing and swinging throughout the gym space. The staff members were super helpful with showing kids how to do everything and giving them helpful feedback about how to accomplish their goals especially on the slope wall! It was so nice to not have to set up or clean up after the party and took away all the party planning stress from this busy boy mom.

    This place is the BEST. The coaches are so knowledgeable, enthusiastic, and compassionate, and they know exactly how to motivate kids to believe in their abilities and grow in confidence and skill while having a total blast. My two kids have very different mindsets when it comes to athletic challenges, yet both of them absolutely love coming here. When I see my kid accomplish something that at first they didn’t believe they could do, it’s phenomenal, and that has happened over and over thanks to the Academy.

    I can’t say enough great things about Ultimate Ninjas Academy! The entire staff is upbeat, positive, and incredibly attentive to the children — you can really tell they love what they do. The energy in the gym is always fun and encouraging, and the kids leave feeling proud and confident.

    I recently needed some assistance with a specific situation, and the team went above and beyond to make it happen. The manager, in particular, was so kind and understanding — she took the time to personally help and made everything so easy. That level of care is rare and truly appreciated!

    The facility itself is clean, well-organized, and very family-friendly. You can tell they put effort into keeping it safe and enjoyable for everyone.

    Overall, it’s a wonderful place for kids to learn, play, and build strength — both physically and mentally. Definitely a 5-star experience all around!

    We absolutely LOVE Ultimate Ninjas Academy. We have been doing their junior ninjas class and both our sons have gained so much confidence and strength. We just had the birthday party for our youngest son today as he turned 4 and it beyond exceeded our expectations. We ADORE coach Shay and coach Sarah and are so grateful for the energy and fun they brought to 14 kids 6 and under in age. I cannot recommend ultimate ninjas academy enough, it is worth EVERY penny. Thank you also to owner Melissa, who was present for our party and got busy in the thick of it with cleaning up and keeping things moving smoothly!

    The Academy is a wonderful place for kids to develop physically and mentally, to make friends and see that with hard work and persistence they can achieve their goals. The trainings are led by wonderful, professional coaches who are great with children all ages, the atmosphere there is very nice. The owner is a great, passionate ninja warrior and a lovely person😊. I can recommend the Academy to every child, you won’t regret the training or open play here! The Academy organizes fantastic summer camps, too. Thank you, wonderful Ninja Coaches😊!

    My kids (4&6) absolutely love Ultimate Ninjas Academy in Naperville! Their confidence and strength has grown SO MUCH since they started. They have also learned how to be a good teammate and how to fall, fail, and get back up and keep trying until they succeed.

    Beyond that, they love every single one of the coaches, love their classes, and they even loved every single day at summer camp as well! The staff always does something fun and different every time we go, and my kids are always very excited to see what they will be doing next.

    We even did our daughter’s Birthday party there and everyone had so much fun! Highly recommend Ultimate Ninjas Academy!

    We originally went to Ultimate Ninjas Academy Naperville to burn off some energy during the cold winter months, but what we found was a second home! Our kids (3, 5 and 6 when we started) have built confidence, body awareness, overall body strength, resilience, determination and so much more from attending ninja classes. They have built bonds with each and every one of the coaches (as have mom and dad), who are incredibly encouraging, thoughtful, and create an environment that nourishes and challenges children to grow each week!
    We’ve participated in open gym, classes, camps, ninjas night out, and have had two birthday parties at Ultimate Ninjas Academy and every experience has been exceptional!!
    Special note about birthday parties - Ultimate Ninjas Academy is the only location I’ve ever hosted a party at in which I’ve been able to relax, enjoy the party, and talk with the guests who are attending. They take care of literally everything! We showed up with the cake and decorations in a box and they took care of the rest! We placed our pizza order with Melissa and the team the week prior to the party and they managed the ordering and delivery of the pizzas for us. They decorated and served all of the food and the cake. The cleaned and packed everything up - truly outstanding service! Both parties I’ve had there I leave saying “I love this place!” Not to mention, we have guests inquire about attending classes at the gym after each party, so it’s safe to say everyone has a great time!!
    If your children are active and always on the go, or if you’re looking to get your kids into something new that only requires a little bit of focus and participants who want to have fun and do their best, then Ultimate Ninjas Academy is for you! We’d give Melissa, Angie, Sarah, Krissy, Shea, and the rest of the team 100 stars out of 10 every single time!!

    Came here for a birthday party with kindergarten aged kiddos and had a blast! My daughter isn’t the most adventurous with climbing/swinging and there was plenty for her to do that was lower to the ground. She even tried the climbing wall! Loved that they had an area to store all our winter coats and bags, and lots of rooms for parents to watch from a safe distance. The party room was a nice size too.

    Excellent place for a birthday party for my 7 year old! Addy, Christina, and Sarah were absolutely amazing with getting the kids excited during the event, getting them all to hand sanitize, cutting the cake, cleaning up, I mean all of it!!! The most hands off party where the kids and adults had fun! Thank you!

    We started my son here with Coach Angie when he was 18 months. At first we questioned whether he would get any benefits out of it at his age. However, over time we've noticed improvements in motor skills and willingness to try new physical activities. Coach Angie is also awesome - patient and encouraging. This location is a bit of a drive from my house but we make it a point to try to come because of how much my son has improved since starting.

    We have loved our experience at Ultimate Ninjas Academy. The owner, Melissa, and her entire coaching staff are all so warm and supportive. I have literally been brought to tears watching how much they encourage the children to go past their comfort zones and achieve what they didn't believe they could do in such a loving and encouraging way. My son is 4, but this program would be great for children of all ages and they offer a variety of training levels. I can not say enough great things!

    I cannot overstate how great Ultimate Ninjas Academy is! I took my 6 y/o for a class, and I loved watching the coaches gently instill confidence in each kid, showing them that they’re capable of doing more than they imagine. My daughter is naturally cautious, so I loved that she felt comfortable enough to try everything in the gym. After that, we had her birthday party there, and it was a fantastic experience. First, and most obviously, it’s the perfect place for 20 kids to get their wiggles out.
