Kaizen Judo Club is very proud to count among its experienced and NCCP certified instructors, featuring Sensei Wayne Erdman, Shichidan - 7th Dan, Sensei Bob Zettl, ChPC, Rokudan - 6th Dan and Sensei Barry Williams, Godan - 5th Dan and many other certified Black Belts who deliver quality Judo programming to its students ages 5-75. Our curriculum was designed in consultation with Judo experts, as well as with certified school teachers.

Kaizen's two Olympic-size mat areas and sprung floor ensure that you can practice our sport safely.

Kaizen's great spectators viewing area, climbing ropes, peg boards and family oriented activities held several times annually ensure that every member of the family is comfortable, engaged and involved.

Our instructors are qualified though multiple governing bodies (the National Coaching Certification Program as well as Judo Ontario & Judo Canada).

The Evolution?

Kaizen Judo Club began as the dream of Sensei Bob Zettl, who after decades of volunteer instructing and coaching for a Judo Club affiliated with the cities of Kitchener and Waterloo Parks & Recreation programs that he founded in 1978, opened his "dream dojo" in 2003. With the help of many of Sensei Bob's students and their parents, especially Sensei Barry Williams, Kaizen Judo Club became a reality. Sensei Bob's wife, Dana has played a huge role in Kaizen's continuing success through her role as educational advisor and registrar.

Since our opening, hundreds of students have been taught by Sensei Bob. He is currently still teaching six days a week. His son Andy, a former Canadian National Judo Team member (and also a 2nd Degree Black Belt) will likely follow in his footsteps and is pursuing further education in Police Foundations, Personal Training and Nutrition.
