About Our School

Sioux Falls Kenpo 5.0

American Kenpo has earned its reputation as one of the most practical and effective self-defense systems in the world. Its strength lies in three core principles: efficiency of motion, effectiveness of technique, and a scientific approach to application. Together, these principles create a system of personal defense that is not only powerful in real-world situations, but also logical, teachable, and accessible to students of all experience levels.

With the evolution of Kenpo 5.0, created by Grand Master Jeff Speakman, the art continues to advance. Kenpo 5.0 expands traditional American Kenpo by integrating ground-fighting concepts and modern self-defense realities, ensuring students are prepared for every range of combat. In today’s world, the importance of sharing this knowledge has never been greater.

Our mission is to provide a place where martial artists of all backgrounds can come together to strengthen their self-defense skills, exchange ideas, and contribute to something bigger than themselves. We believe growth happens best in community—through collaboration, mutual respect, and a shared commitment to personal excellence and the common good.

Started by Instructor Russell Knoeppel, our school was established to bring Jeff Speakman’s Kenpo 5.0 training to the Upper Midwest. Here, students are taught the true essence of Kenpo: developing not only the skills of a warrior, but also the mindset of a scholar. Training goes beyond techniques, fostering disciplineconfidencecritical thinkingand character.


Our school is more than a martial arts school; we are a family and a second home where instructors and fellow students support one another—on the mat and in life. Whether your goal is self-defense, personal growth, or lifelong mastery of the art, we are committed to helping you become the strongest version of yourself.

As a martial arts school we specialize in the art of Kenpo 5.0 as revolutionized by Grand Master Jeff Speakman. We have acquired a variety of skills which we filter through our classes to our young and eager to learn students incorporating Brazilian Jiu-Jitsu (BJJ), and the art of Kenpo Karate all into one amazing art.

We strengthen our school and students physically through the use of bag work and power workouts multiple times per week. We are not just an art of kicking and punching but one of close-in contact self-defense which we strive to instill into every single student. We believe we can empower the youth with skills and knowledge of the art bringing out the confidence and ability to protect themselves.

We have a variety of programs available for all genders, ages 7 and up, and backgrounds such as group and private classes.
