We are in deepest shock and pain to learn of our dearest friend’s passing. Jack: we will continue to honor your memory and remember you as the wonderful judoka and friend that you are. We can only regret that our time was too limited. Thank you for everything you’ve done for us, our dojo and our students. I hope you knew how much of a difference you made in so many people. You are the embodiment of Senshi — a warrior, to us. We hope you are in a better place. The world misses you already friend ❤️
