Awesome gym. Great welcoming environment. The karate and the Brazilian Jiujitsu instruction is very high level. Some super tough rolls in grappling. An excellent summer program for the kids when they are off from school. I have visited multiple times and it was always an amazing experience. Highly recommend if you are in the area and looking to get into the martial arts.

Hands down the best!!! My 3 girls have been with Johnny and his team from day 1 of karate. Every instructor is amazing with kids. They instill the perfect balance of discipline, integrity and fun into the study of karate.

Johnny karate and staff make our 3 year old empowered to take risks, be even more confident, and respect himself and others. I love my kickboxing class for moms and daddy is addicted to the jui-jitsu classes.

We couldn’t be happier with our experience at Johnny Karate! Our son has grown so much in a short time—he’s so excited to go that he asks us every day! The instructors bring such great energy and genuinely care about helping each child get the most out of every class, shaping them into future leaders. We’ve seen a huge improvement in his focus and concentration. I’ve also loved taking the adult classes on Saturdays whenever I can squeeze them in before his. Highly recommend!
