I am very sad to hear that Sensei Leon has passed away. I am grateful to have met Sensei Leon at several international gasshuku's. I was always very impressed by his unique teaching skills, his knowledge and dedication, and his kind and warm personality. He was always friendly and ready to share his experience related to karate training as well as other areas of life, typically accompanied by a joke or a twinkle of the eyes. Sensei Leon will be truly missed in the IOGKF family.
Please extend my sincere condolences to Sensei's family and students in Israel,
