Kaizen Judo Club: Run by a Family for Families

From our family to yours...

Bob, Dana, Becky and Andy Zettl have a collective 85+ years experience in the sport of Judo. Among them is a former National and Provincial Coach, a two-time Canadian champion and former Canadian National Team member, a Montessori teacher, and a certified public school teacher.

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 family oriented activities that are held several times annually ensure that every member of the family is comfortable, engaged and involved.

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 3rd Degree Black Belt) will likely follow in his footsteps and is pursuing further education in Police Foundations, Personal Training and Nutrition.

Our Facility

Our newly-renovated 2000+ square foot facility holds two Olympic-size mat areas, change rooms with showers, a reception area, a small store and best of all, an awesome spectator area where spectators have an overhead view of the mat area.

Most importantly, Kaizen Judo Club offers its students a state-of-the-art sprung floor, designed to minimize injuries and soften impact. Of course, we also love our climbing ropes, pegboards, crash mats and all the other various accessories that help students learn.

Unique from many martial arts facilities, is our sound system that we like to use to play music to get students pumped up during their various Judo and cardio workouts!
