    Summer Camps

    Looking for something AMAZING to offer your kids over break? Send them to Ultimate Ninjas Camps, where they will learn how to tackle obstacles as seenon TV. At Ultimate Ninjas it's so much fun to get back up and try again.....

    At Ultimate Ninjas, we instill self-confidence, acceptance, and a true hunger for tackling obstacles with a positive mindset. The best part: we have a BLAST doing it! The camps are designed by 3 time American Ninja Jesse Labreck, you will not find a more positive environment where kids can show up, be valued for exactly who they are, and discover what they are uniquely capable of achieving.

    During camp, kids are grouped together by age and rotate through stations where they are coached on each obstacle. After learning how to tackle the obstacles, they have time for open play so they can pick their favorites and spend extra time on the obstacles they want to master or just enjoy! At the end of camp all kids will get a chance to run through the course with their coaches just like you see on TV!

    We just celebrated my son's birthday at Ultimate Ninjas Oak Creek. The kids had a blast! The staff was attentive and involved in coordinating the supervised open play. The facility was clean and the communication and check in process was smooth. We would 100% recommend this location for any parents considering having a birthday party here.

    We attended a birthday party and it was great! We were in the little ninja area and the kids were fascinated by the warped wall with the slide. Pizza was delicious and the staff was very friendly!!

    If you're looking for an active field trip for kids who love to climb and try new things, this is 100% the place to go to.Brought my class here on a field trip all the way from Madison and I can say it was for sure worth the trip! Mike, Nathan, and Marquez made sure my class had an amazing time on all of the ninja equipment while also making sure the kids were safe on new obstacles. They even provided us a room for lunch and to keep our things in.Thanks guys!

    We switched our two girls to Ultimate Ninjas Oak Creek from a gym in Hartland we had been at for a couple of years. It is a little longer drive, but it is easily worth it! The staff is very encouraging, the obstacles are super fun and the classes are well structured. Ninja is a great sport for kids of all ages, and Ultimate Ninjas is the place to do it.

    We had the honor of being the first party that they hosted. My daughter’s 7th birthday party was amazing! Mike followed up before the party to confirm everything and answered all of our questions. The staff was so awesome! Marquez and Nathan (as well as another young lady) interacted with all of the kids. They were very involved in assisting us with the set up of the room (we had themed tablecloths and balloons), pouring drinks, passing out pizza and cupcakes. They even stayed and sung happy birthday. It was truly a great experience that you won’t get anywhere else. You can tell everyone truly enjoys what they do. We will definitely return back, especially to check out those Ninja classes. So what are you waiting for??? Book today!!

    We had the best experience here today! The staff member working in the little kid area was awesome. She was super helpful and encouraging to both of my kids (2 and 5). I chatted with the owner a bit about the classes and he was very friendly and informative. We’ll definitely be back!

    AMERICAN NINJA WARRIOR -- "Baltimore City Finals" Episode 1110 -- Pictured: Mike Silenzi -- (Photo by: William Gray/NBC)

     

    Mike is a 11 time American Ninja veteran and 7 time Las Vegas finalist. His nickname on the show is “The Stallion” and he can be seen on season 4, 5, 6, 7, 9, 10, 11, 13, 14, 15, and 16.

    Michael grew up a competitive gymnast and by the age of 12 was ranked 37th nationally. In high school he made varsity as a freshman for pole vaulting and for fun was involved in a breakdancing group. He transitioned into ninja warrior training during college at Northern Illinois University where he earned his master’s degree in Physical Therapy. “I currently supplement my obstacle training with rock climbing and water sports including slalom skiing, bare-footing, and wake boarding.”

    Michael hopes to grow the ninja community and promote the “NINJA LIFESTYLE” which involves being active, eating healthy, treating people kindly, and doing the right thing. “Competing on TV gives me a platform to be a role model. Whether I complete an obstacle or fall in the water I measure my success based on if I can make a positive difference in someone’s life.”

    What our customershave to say about us


    We just threw my daughter's 6th birthday party here and it was wonderful! They were very helpful and accommodating. Our guests had a great time and the staff assigned to help our party could not have been nicer. I would recommend this for a party venue (or just a fun open play/class activity) to anyone!Hannah B.
    I brought my 11YO son today for open gym and he absolutely loved it! It definitely became more crowded after 12:30, but the staff was great and offered assistance when requested. The obstacles were just like the show and are easy to try, but challenging to master. We will be back for sure!Amy J.
