KCA Jiu Jitsu & Muay Thai Rancho Cucamonga

“After spending about a month researching and visiting nearly 10 different studios, I was starting to lose hope of finding a place that offered both BJJ and Muay Thai under one roof. Most gyms only had one or the other. Then one Saturday morning, I got lucky and happened to catch Charlie at KCA just before closing time —and I’m so glad I did. From day one, I’ve had zero regrets about joining. The environment is incredibly welcoming, and the community here makes you feel at home right away. Training is the perfect mix of focus and fun—every class is structured, informative, and engaging. Charlie and Joel are fantastic instructors who genuinely care about your growth and make every session something to look forward to. If you’re thinking about checking it out, do it. You won’t regret it!”

“My daughter has been attending their classes exactly 3 years now. The attention and guidance that the sensei was beyond my expectations. There is a community, Between the children and the parents. It's literally food for your soul! Thank you to Charlie and the beautiful Mrs. That make this possible ❤️”

“My daughter tried a couple of classes (jiu jitsu & muay Thai) here and loved it. The environment is very welcoming and family friendly. They offer pretty cool amenities, which I appreciate. Cool tunes play in the background, nice layout, and nice open air flow so it doesn’t have that stuffiness to it. (I might sign up next) Sensei Charlie, Ms Marie, and Kru Joel most definitely bring the VIBE CHECK to the place ! Thank You All!!”

“It was a pleasure teaching you Muy Thai and BJJ. Very proud of you and looking forward to seeing you in the afterlife. Shalom Long Live the Real GM of KCA Nelson Cortes”

“My son has been attending for 3 years and we couldn’t be happier. His skills, coordination, and discipline have improved every year since starting. Sensei Charlie is a master of his craft and the entire dojo breeds a family atmosphere. Great life lessons mixed with solid JJ skills is at the heart of KCA.”
