This weekend Mr. Joe and Max Karstadt travelled to Hood River, OR to support the ITF Tournament. This tournament was beautifully organized and very professionally run. We had the opportunity to perform Patterns & Sparring in front of Masters, Grand Masters, and several Highly Qualified Internationally recognized ITF Umpires (the exact umpires you would have at the World Championships level!)

Mr. Joe - Patterns: GOLD🥇 Sparring: GOLD🥇
Max - Patterns: GOLD🥇 Sparring: GOLD🥇

We couldn’t have asked for a better experience, and this will certainly be a tournament we look at adding to our Annual JSK Competition calendar!
