Karate-Character-Life Skills

We are a martial arts school that teaches much more than just kicking and punching. Patience, kindness, anger management, goal setting, respect, and self-awareness are a few of the character development skills that we practice within our curriculum.

Our state of the art training facility provides the perfect backdrop for developing the skill and determination needed to succeed in martial arts.

More than Kicking and Punching!

We have drop-off events where parents have the option to drop off their children and do their own thing. We also host several family-centered events throughout the year, where it’s a great time to connect and spend some time together! We have Birthday Party options for karate and non-karate students!
