“My son has been with AKS going on 14 months! It has been a very positive experience watching my 10 year old build lasting self confidence right before my eyes. My child feels exceptional when he earns his stripes and advances belts! Coach Nick inspires his students to become not just better athletes, but a better people as well. AKS atmosphere is engaging and positive! You won't be disappointed! FUN FOR ALL AGES!"
Rehana H.
“Great place to learn kickboxing and Jiu Jitsu both for adults and kids. The coach is professional, patient and supportive. It is a great group of kids and adults that support each other in learning and improving each other's skills. Myself, teenage daughter and 5yr old son take classes. My husband should be starting soon. I'm so glad we found AKS!"
