From the reviews
My son attends ONE FOR ALL TAEKWONDO. The master here is incredibly passionate and truly loves the kids. I never imagined my child would enjoy taekwondo this much. Last week, we even celebrated my son's birthday at the dojang, and he had such a wonderful and fun time.
This Taekwondo studio is truly a hidden gem. Not just because of the facility itself, but mainly because of Master Roy. He takes so much time to get to know his students and truly wants what is best for each and every one of them.
The location is very clean and wide. The kids are very friendly :) Master Roy is kind and active that parents are satisfied with his teaching and attitude for kids. Also he opens special events sometimes that kids love to stay here😆 새로 생겨서 깨끗하고 넓어요.
My nephew recently enrolled in this Taekwondo class. My 6year old nephew joined because it looked fun, but I was surprised to learn that Taekwondo not only provides fun but also teaches children manners, proper thinking. Thank you, Master Roy, for always being passionate and doing your best.:)
Your first taekwondo class at ONE FOR ALL 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.
