Ken Kranzman

Ken Kranzman is the head coach and founder of Underground Jiu Jitsu in Dousman, Wisconsin. A black belt under Ryan Courtney, Ken brings years of experience both on the mat and in developing structured, fundamentals-driven programs.

His coaching emphasizes more than technique alone—focusing on progression, pressure, and the ability to connect takedowns, positional control, and submissions into a complete system. Ken leads from the front, continuing to train, learn, and challenge himself alongside his students.

Known for a straightforward, no-nonsense approach, his goal is simple: create an environment where students can train hard, improve consistently, and develop real, applicable jiu jitsu.
