Yi Sport Seattle is full service martial arts gym and athlete development center for both youth and adults with a focus on creating good fighters. Our coaches Marshall and Isaak have been practicing taekwondo together for almost 20 years and have been training at Yi Sport since it was founded 16 years ago. “We pride ourselves on teaching our student’s work ethic and giving them the motivation to grow stronger. Come and visit us to see why no other taekwondo team in Washington works as hard as we do.”
