JSK TaeKwonDo has set its home in between the wonderful neighborhoods of Arcadia and The Biltmore! Our program specializes in children's classes ranging from ages 4yrs and up. Through positive reinforcement, our martial arts classes teach self confidence as well as the amazing respect, focus, and self control that you'd come to expect from a Martial Arts program. Come by for your first class and see why all of Phoenix seems to be raving about this program!!!

The relationships we make at these international events last a lifetime, and they are what make my job, and the life we’ve chosen, so exciting.
Whether it’s in the form of confident, experienced, and trustworthy coaches to step in when needed… training partners and likeminded practitioners always looking to better themselves and others around them… or most importantly, in the form of encouraging words from an opposing coach that is more interested in the growth of a child than his athlete “proving they are the best”. I am grateful to all of you that helped encourage, build, and support my Team at the 2025 Holland Cup, and I hope to be able to return the favor one day.

And also, a huge shoutout to the other USA competitors from in Maryland. They were also ready to step up and help TEAM JSK if needed. They had an outstanding showing from sister Patricia and Jessie DeArmas. .dearmas.tkd earning 🥉 in sparring and earning bronze in patterns and 🥇 in sparring! Well done ladies, and way to represent for Team USA!

SUNDAY TRAINING with International Guests. Instructors and students from different countries coming together for one single purpose… bonding through TaeKwonDo - One of our favorite additions to the Holland Cup.
This year I got to share the experience with my daughter and a few young students. I absolutely love this part of the TKD world 🥋

Not ALL the best pictures are the ones on the Mats!
Tournament days are chaotic and everyone on TEAM JSK, competitors and supporters alike, stepped up when it mattered the most. Whether it came in the form of making sure the team was fed/hydrated, or running back and forth across the gym to grab another teammate or their equipment etc, every act helped. We are more than a team, we are a family, looking out for each other and I am very proud of how we all came together.
