Kempo blends the power of Japanese Karate with the fluidity of Shaolin Kung Fu. The fusion of these complementary styles creates a dynamic, effective self-defense system.
As the first true mixed martial art, Kempo combines tradition with adaptability. At USSD, Kempo’s legacy and innovative approach provide a life-changing path to personal empowerment.
Due to its inherent adaptability, Kempo forms to the practitioner; not the other way around. As students grow in their training, they will become equipped and confident with self defense skills that fit their unique needs.
Kempo is a living, breathing, martial art that is constantly honed and refined to reflect modern day needs. USSD students receive the benefits of the traditional martial arts while sharpening the real world effectiveness.
