At…read morethat age, other activities just weren't challenging or engaging enough for him, but Master Rigg was willing to give him a chance. Master Rigg is incredibly patient and wonderful with all of the kids. He takes the time to teach them in a way they can understand for their age group and makes sure they actually understand what they're doing instead of just going through the motions. You can truly tell that he cares about helping each child learn, grow, and build confidence. Master Mary is also incredible! She is so patient, kind, and caring, and you can tell that she genuinely cares about every child who attends class. She creates such a positive environment and makes the kids feel comfortable while still encouraging them to do their best. Instructor Ari has been such a wonderful addition as well. She absolutely adores our son and treats him so well. She is incredibly patient with him and with all of the kids, always showing them respect, compassion, and encouragement. We are so thankful we found Action Martial Arts. The instructors truly care about the kids, and that makes such a difference. We highly recommend Action Martial Arts to any parent looking for a place where their child can learn Tae Kwon Do while also building confidence, discipline, and great relationships with their instructors!

After being on the sidelines for about two months watching him practice, I decided that it would be good for me to join as well for my own well-being but also for a way to bond and connect with my son. I've been training since June 2025. The friends I've made since joining the gym have been amazing. Once you get yourself established, you will be amazed about the community of people. People from all walks of life train at this gym. It is friendly. It feels safe. It's clean, which is important, and it's just a great time. Even after an hour and a half of getting smashed, I get my car with a smile on my face Looking forward to going to class in the next day. I certainly suggest anyone who's interested in the sport of Jiu Jitsu give this gym a try.

Shy and lacking confidence, we set out to look for a martial arts that would help him come out of his shell. We've been to various martial arts schools to watch family members tests. But, what we found different about US taekwondo center was the environment! When we went in, we found that there were no mirrors! instead, there are encouraging posters on the wall. We believe this is a great way to build Better focus! The school is always clean and the colors really bring you in. When we first met master shin, we only got good vibes from him. We started off with the free trial session, and right away we noticed a difference in our son. We were shocked that he was able to bring out a yelling champion in our son, who gets very timid in new environments! When we tell him it's time for taekwondo, he gets super excited and is pumped for a work out. Our son has shown much improvement in fitness, confidence, and respect at home. Thank you master shin! We always recommend US taekwondo center to our friends and family. Take advantage of the free trial class, and just try it out. Trust me, you'll see a difference just from the first class. Thanks again, master shin!

I'm very disappointed with our experience at this taekwondo school. In my opinion, there is too…read moremuch focus on moving kids through belts quickly instead of making sure they truly master the skills required for each level. The program requires a large payment upfront covering training toward black belt, but there are also additional charges each time a child tests for or receives a new belt. Because of the way the program is structured, I felt there was constant pressure to move the kids to the next belt very quickly. As a parent, I would rather see my child spend more time developing proper technique, discipline, confidence, and earning each belt based on skill--not feel rushed through the belt system while continuing to pay additional belt/testing fees. I strongly recommend that parents ask for a complete breakdown of all upfront costs, belt-testing fees, and how long students normally train at each belt level before enrolling.

He focuses not only on students learning techniques but also on understanding the philosophy behind the art. He is very caring, but will always hold you accountable to do your best. If you are an adult considering Taekwondo, I highly recommend CUTC! Children, teens, and adults can all receive excellent training from an experienced and caring teacher.
