Without…read moredoubt or hesitation, I can say Master Givans has one of the very best TAE KWON DO programs in the entire country. Over the past year and a half, our boys have improved remarkably.

Whether you or your child's interest lies in traditional TAE KWON DO, or sport TAE KWON DO, you will not find a more comprehensive and well rounded program than that which Givans TAE KWON DO has to offer. My family and I live in Napa. We commute to Antioch four days a week for training, just the commute takes about three hours there and back. Training under Master Givans is worth every minute of that commute. -Michael N

I used to train here actively from 1993-2009 (even back when it was USKO, not USKS!). Received my…read moreblack belt in 2003, and continued to train and teach for the rest of my time there. When I was there, the Krupas were my main instructors. I trained and learned from all of them. This place is not just about self-defense. It's about character-building and humility, both applicable traits in their motto "Power under control". Although the main focus is karate, once I got my black belt and had thus mastered just the basics, my training became more focused on specific martial arts, such as judo and aikido. In order to get the most out of my training, I took advantage of many opportunities provided by the dojo, including special training sessions and a special black belt-only class. Shihan Ron was my main instructor, and he was fierce in his teaching - making sure that we were well-disciplined, had good form, and treated each other with respect. A true master of the arts, I loved training under him. One of his sons, Sensei Josh, was an instructor that I would always look forward to learning from (horrible grammar, I know). From an early age, he actually failed me on my green-belt test. I was devastated. From then on, I knew that in order to progress, I would have to give it my all. He taught from example, and never had us do anything that he couldn't. When I tested for my first degree black belt from here, I came out of the test knowing that I earned it. Having my Senseis give me my black belt was recognition to me that my kata form, sparring, and grappling were good enough to truly begin my focused training in the arts. Although I wasn't able to fend off a few black belts at once (part of the test), by the end of the few hours I had a much better understanding of how to focus even during situations that were not advantageous. But most of all, I recognized that my black belt did not mean that I was the best at self-defense; rather, that I was good enough to begin training. My only gripe about the dojo (and it may have been fixed since I left) is that a lot of the students, I felt, got promoted through the ranks without being ready. I saw some of the newer black belts (as well as the lower ranks) and felt that they should have had more training before they received it. Maybe that's changed now though.

I can't say enough about how pleased our family has been with USKS, its family atmosphere and…read morequality training. Our kids began at ages 5 and 7 and have loved it. Naturally, I had a lot of questions about what they would be learning and the pace that the class would go. Sensei Joyce clearly demonstrated the many years that she and her family have been instructing students as she kindly and thoroughly answered all of my questions. I have seen first hand our children grow in their awareness of their surroundings and gain the concentration and discipline that it takes to move through the ranks of this quality martial arts program. When I asked my now 8 year old daughter her opinion of USKS, this was her reply, "USKS is a great place to go to karate. It's different from other karate places because it's Christian and they help you to memorize Bible verses and character traits and what they mean, like attentiveness. They want you to apply them to your life. They have special rewards for people who seem like they work their hardest. They treat everyone equally and really help you learn." My daughter has asked for a private lesson with Sensei Joyce for her birthday which is coming soon and I'm delighted that she sees the excellence in training that she would receive. If you want to be a part of a family community, fun activities, an atmosphere of self-discipline and respect, check out USKS. I wouldn't go anywhere else!

We were invited to an "invite only" multi-gym rumble, where kids sparred in a no-points, no-pressure environment. All the kids from my dojang loved it. My boys also attended a sparring clinic with Coaches Arven and Kris, both world-class level athletes. The individual coaching was top-notch, and my kids thoroughly enjoyed training with them. The dojang is well-kept, and the mat is nicer than standard tournament mats. Parents can watch from the hallway through large windows. The facility includes a snack bar, and the bathrooms are clean. **Pro-tip:** Park in the parking lot near the dojang--it's a shorter walk and usually has more open spots. Overall, Sparta Taekwondo offers an excellent environment for both training and community. Highly recommend!
