Yehoshua Kadosh received his 8th Dan rank, Promotion to Kyoshi, and Daishihan Menjo (Master Instructor's Teaching License) from 10th Dan Grand Master D'veed Natan on January, 1st 2020.
Kadosh, Kyoshi is a graduate of the Wingate program at Tel Aviv University, studied "kappo" (resuscitation techniques), and trained in first aid with Magen David Adom professionals. Teaching has become a specialty with Kadosh, Kyoshi not only because of the patience and care that he shows to his students, but also because of his methodical approach to teaching and attention to detail that ensures complete understanding of the material demonstrated. Yehoshua is one of the very best students that I have ever taught. His attention to detail, work ethic, and uncompromising ability to see the "facts" regarding technique functioning as would occur in real time reality, makes him truely a Teachers' Teacher. J.
