3rd Dan Senior Instructor Jonathan Katzman began his martial arts path at a young age with Tang Soo Do, where he obtained a second degree black belt.  In college, he switched over to Taekwondo, starting over at white belt. There he trained under Master CJ Yong Chang, obtaining his first degree black belt.  After moving to San Francisco, he re-obtained his first degree (and later his second and third degrees) at Hwa Rang Kwan under Master Steve Rapport, with additional Kukkiwon certification and training under Grandmaster Martin Marcus.  He also began kickboxing training as well.

Jonathan is an avid competitive sparring and poomse enthusiast, having competed in the Eastern Collegiate Taekwondo Conference (ECTC) in college.  After graduation, he shifted his focus to coaching, and has coached several gold medalists at USTA and AAU state- and national-level tournaments. At HRK, Jonathan teaches general Taekwondo once a week, and occasionally leads classes in sparring basics and Olympic-style sparring.

Outside of Taekwondo, Jonathan is a software engineer with a passion for music, video games, board games, and puzzles.
