  • WTC Martial Arts studio is like another home to me. I love it there. I have been going for 3 years and I will definitely keep coming back. Grandmaster Kim is an amazing teacher. He's patient, kind, funny, and the children love him. His two sons and many instructors teach as well. They all do a wonderful job and the kids enjoy having fun while learning. While some studios may rush kids from white belt to black belt, WTC doesn't do that. They are patient and are always eager to lend a helping hand to improve any student's technique. I definitely recommend this studio to anyone who is looking for the best place to learn tae kwon do.
