FOUNDER/HEAD INSTRUCTOR Joe Karstadt - 6th Degree Black Belt - World Champion - Member of The TaeKwonDo Hall of Fame
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!!!
