Clean facility, extremely friendly and helpful staff. You tell that everyone that is there loves being there, whether training or working. Staff is so helpful to younger ninjas helping and encouraging them and giving them advice, even when not on the clock. Fun atmosphere with tons of ninja obstacles and equipment!!

Ultimate Ninjas has been the absolute best for my almost 5 year old son. He’s been taking weekly classes for almost a year now! Not only is he gaining strength and athletic skills, but his perseverance and confidence are growing, too! The community is so incredibly uplifting, supportive, and positive. We love it here!
