Meet our instructors
Jim Santiago DeLeon founded this club in Petaluma in January 1970. When he retired in 2007, Sensei Henry Kaku took over as head instructor. Many of today's instructors first stepped on the mat as children. Sensei Davin started here at age 5 in 1992, and he's now our assistant head instructor.
We're a 501(c)(3) non-profit, run entirely by volunteer instructors. Class fees are collected by Petaluma Parks & Recreation and go toward mat time, equipment and insurance, which keeps judo affordable for Petaluma families. We do this because we love judo and want to pass it on.
Rank earned here counts anywhere.




No appointment, no experience, no cost. Tuesdays and Thursdays at 5:30 pm — stay and watch, or step on the mat.
