the Personal Trainers of the Martial Arts

private martial arts classes

Unlike traditional martial arts schools that focus on large group classes, we specialize in private and semi-private instruction where you or your child receives personalized attention from expert instructors—just like working with a personal trainer at a gym, but for martial arts.

Our comprehensive program combines Karate, Kung Fu, Jiujitsu, and Self Defense into one complete system. With our unique approach of private lessons combined with age-specific group classes, students progress 2-3 times faster than traditional group-only programs.

Training History: "I started my martial arts journey in 2008. After exploring a variety of sports and activities growing up, I discovered that martial arts provided not only a way to stay active and fit, but also gave me more confidence."
