Our History
Defiant Jiu-Jitsu’s doors opened to the Woodbury community in late 2024. Owners Dave Margraf and Kenzie Swartz established a school that is truly theirs to bring the local community together through Jiu-Jitsu. Dave has trained for over 20 years and nearly a decade as an instructor, earning his black belt in 2016, winning multiple IBJJF competitions during that time. In addition to running our youth program at Defiant, Kenzie is a certified personal trainer with a Bachelor’s degree in kinesiology (exercise science) and a minor in sports coaching. She offers personal training for general fitness and specializes in programming tailored to Jiu-Jitsu athletes. With all their experience supporting them, Dave and Kenzie have built a strong culture where positivity grows through camaraderie and encouragement between students and instructors.
