We’ve been coming for months and love this gym. We took the summer off and are back and are excited to see the facility is under new manage with great changes implemented! They are cleaning the space between classes and have implemented a new class program model to reduce waiting times between obstacles. The coaches really care about the kids, they are positive, encouraging, and accommodating to the needs of the class.

Ultimate Ninjas in Noblesville is a wonderful facility with great staff and a perfect setup for a wide age range of kids. My children gained so much confidence from their classes, and I would recommend it to anyone. Even my shy, nervous child became an ultimate ninja, and the staff was very patient and professional. We love Ninjas! ❤️

I am the Special Needs director at White River Christian Church in Noblesville and we partnered with Amanda and her team to host our February Respite night. We had an absolute blast at Ultimate Ninja's facility and the staff was a blessing to our students. They helped create fun and creative games while adjusting on the fly to meet the needs and desires of the students. The staff adapted multiple courses and created a space where our students living with a disability could belong and have fun together. Not every place is welcoming to do this and they were excited to! There were smiles on everyones faces and the volunteers enjoyed the courses as well! I recommend Ultimate Ninjas to anyone looking for a fun place for kids or adults! We will be back!

I attended a child's birthday party! It was awesome. They kept the kids busy going from one competition area to the next, as a group, so nobody was left out! They also assisted the kids to make sure that they succeeded if at all possible! The kids had a blast! Everyone cheered the kids on as they competed! Excellent place for a party. They also had rooms for eating the birthday cake and exchanging the birthday gifts.

This is quickly turning into one of our favorite places in Hamilton County. My 5 year old son attends the minis class. The facility is clean, well thought out, and constantly innovating. Coaches are kind, patient, and work well as a team. Keagan leads the pack and I have seen him seamlessly manage classes, phones, teams, and the occasional mini crisis. Thank you for your commitment to providing an awesome experience for everyone!!
