Erik “Thor” Bartkowiak is a Brazilian Jiu-Jitsu black belt under Thaisio Feliz and founder of Warrior’s Garden Jiu-Jitsu.

With a focus on traditional Brazilian Jiu-Jitsu, but utilizing progressive teaching techniques that he developed as a teacher, Professor Thor emphasizes fundamentals, control under pressure, and long-term skill development. Maintaining the traditions, customs and history of Brazilian Jiu-Jitsu are just as important as the techniques. His approach to teaching is centered on creating a structured, supportive environment where students of all experience levels can build confidence, discipline, and resilience through consistent training, while feeling encouraged to explore the “art” side of the martial art. 

Professor Thor believes that Jiu-Jitsu is more than a martial art—it is a powerful tool for personal growth. His instruction reflects this philosophy, helping students develop not only technical ability, but also the capacity to remain calm under pressure and respond rather than react in challenging situations.

Through Warrior’s Garden Jiu-Jitsu, Professor Thor is committed to building a strong, inclusive community where individuals can train, grow, and support one another both on and off the mat.
