"Best summer camp for your money! Camp counselors (and plenty of them) keep the kids active and well supervised. So many special activities like bringing in large inflatables, petting zoos, and games. Kids come home happy and exhausted ! Thank you! Best summer ever!"
"I took my boys here to try something new. Myself and wife did martial arts growing up and in our Marine Corps careers. We were hoping they would love it too. They do!! My oldest has selective mutism and this has helped with confidence. Somebody *squinty eyes* even got me to sign up too. The whole team is great. The other parents make you feel welcomed and a lot of us have crossed paths taking our kids to other things like swim or gymnastics. 10 out of 10 would recommend. Plus for all the programs they have as well! Date nights, after school programs, and camps."
"We’ve been with KISA for a couple of months and they have completely blown us away! We came from a previous dojo of a few years and it was an incredibly hard decision to leave but at the end of the day, our investment was well worth it with KISA and they proved that within our 1st week there. They were incredibly kind and generous. They also impressed us with their attention to detail and commitment to providing students with all the tools needed for self defense. We love that they also offer so many different options for class times and different types of classes like competition teams, Brazilian Jujitsu, Boxing etc. 10/10!!!!"
"It has been a month with KISA.Here, I experience a dynamic, pleasant & naturally disciplined environment.Each person here is so friendly and supporting to lift up your energy.Thanks to dear Alana Ma'am for the initial words that helped me to go forward with the decision.I look forward for a beautiful journey with KISA. ..& with Sensei,I feel exactly at the right space..🙏🏼Thankyou!"
