I joined Traditional Taekwondo in 2019 with my two kids. It was just supposed to be something fun I…read morecould do with the kids, but I absolutely fell in love with it. Even through the pandemic, Master Johnson went above and beyond to keep students engaged, whether that meant classes via Zoom or classes in the park. I have never done a sport in my life, and this past spring (2025) I got my black belt - at age 51! The classes are rigorous and the instructors are extremely skilled. In addition to getting a great workout and learning an incredible traditional martial art, I have discovered a community that is supportive and dedicated. I highly recommend Traditional Taekwondo to students of all ages.

The staff here was nice enough and they seem to know what they are doing. The low review rating is…read moremostly about my perceived value (or the lack of it) in attending training here. Attended a few training sessions at their much reduced "teaser" rate. They REALLY pressure you to sign up for an annual, pretty non-breakable contract. Their monthly contract cost is pretty high considering that 99% of the training consists of exercises that I can do all by myself... such as running around the perimeter of the gym, playing jump rope, pushups, situps and so on. I signed up for this training because I wanted to learn something about Korean martial arts but that training was never forthcoming. Almost all of the students are young kids. Some VERY young. I was easily twice as old as the next oldest student. If you're a parent and don't mind paying $100/mo to send your kid to a PE-oriented day care center, then this could be the place for you. But if you are an adult looking for intensive martial arts training you may well find the curriculum here disappointing. Bottom line was that I felt I was paying a LOT of $$$ for "training" that just wasn't worth the fee. If all someone wants is an intensive PE workout, there are gyms around that charge in the $10-$15 per month range for that sort of service. I would have given this place one star except that it probably is a good venue for kids who have parents with unlimited funds.

I'm happy with the improvements I've seen in his behavior after class, even if most of the lesson's impact fades away within a day or two. Thankfully, another class is right there on the horizon! Tuition is reasonable, and there are plenty of available time slots for the various programs. Attendance in any time slot is *not* mandatory, at least for the Tiny Tigers program: you're free to bring your student to any available class for their program, throughout the week, depending on your schedule and flexibility. That's a nice touch that's not always offered at other dojangs and dojos. The staff at World Class Martial Arts somehow manage to corral more than two dozen kids at the same time, hold their attention for a half hour, and even impart some lessons (both physical and mental), with a reasonable amount of success. Sure, sometimes a child (often mine! haha!) will require some individual attention to get them to follow instructions and get them back on track, but the "sabom" (instructors) here are quick to notice distracted kids and move to intercept them, often dividing the troublemakers into groups separate from the more attentive students, and giving them personalized instruction. It's a good system, and it works! Gam sa ham nida!
