From the reviews
I'm not sure if there are words to explain how amazing JSK and Master Jang are. We began attending JSK just before the pandemic hit in March 2020. Throughout the pandemic, Master Jang FOUND ways to keep his students engaged until in person classes could be offered again.
Master Jang is awesome! My daughter loves going to tae kwon do every week! She never had interested until we went in and he made us feel so welcomed. My son originally wanted to do kwon do but my daughter after speaking with Master Jang decided to give it a go!
We highly recommend JSK! My son started off very shy and didn’t participate - Master Jang and his staff were all super supportive + kind to him and made him feel welcomed! I feel like these classes help build his day to day confidence tremendously!
My 8yo girls started classes in the spring of 2023. Since then, I’ve personally observed (as well as heard from many others) how absolutely amazing Master Jang is as a TKD trainer. He genuinely cares for his students and has a unique way of balancing discipline with lighthearted humor.
Your first taekwondo class at JSK Martial Arts Taekwondo
Nervous about walking into a taekwondo school for the first time? Almost everyone is, and good instructors expect beginners to come through the door. Here's what to know. What to expect: a typical first class is a warm-up, then drilling basic stances, blocks, and kicks with a partner or on pads — not hard sparring. Rest whenever you need to; no one will bat an eye. What to wear: loose athletic wear you can move in (or a dobok if you have one); you'll train barefoot on the floor. What to bring: water and a positive attitude — many schools lend a loaner dobok for a first class, so it's worth asking when you call. As you keep training you'll get your own dobok and belt, and sparring gear (mouthguard, headgear, and guards) once you begin sparring. Sparring eases in gradually, once your fundamentals and forms are solid. Arrive 10–15 minutes early to sign a waiver and meet the instructor. It gets easier fast — most people feel far more at home by their third class.
