Quick Review: Ji Sung Taekwondo is far more than a martial…read morearts studio - it is an extraordinary community led by passionate, highly skilled instructors who build confidence, discipline, respect, and leadership in every child. From transformative classes to unforgettable birthday parties, the staff consistently goes above and beyond to create a positive, empowering experience for both children and parents. Detailed Review: Our family has known this taekwondo studio since my brother and I were children. Some of my fondest memories growing up were attending TKD tournaments with my parents and cheering my brother on from the sidelines. Life has certainly evolved since then - my brother and I now have families of our own, and while we may no longer jump five feet in the air to break boards with a single kick (or perhaps we still can!), one thing has remained constant: the exceptional community at Ji Sung Taekwondo. Over the years, much has changed, yet the studio's core values have remained unwavering. Ji Sung Taekwondo continues to cultivate confidence, resilience, discipline, respect, teamwork, cultural appreciation, and outstanding martial arts skills - all while creating an environment where children genuinely enjoy learning. Not every instructor possesses the rare combination of being engaging, encouraging, patient, and deeply invested in their students. Just as classroom teachers vary, martial arts instructors do as well. At Ji Sung, however, you will find highly skilled, compassionate, and remarkably dedicated instructors who consistently go above and beyond for every child. After researching numerous TKD studios, I can confidently say this is the most impressive team I have encountered. As a parent, my goal is to raise confident, respectful, and capable future leaders, and Ji Sung reinforces those qualities beautifully. One of the most impressive things about the instructors at Ji Sung Taekwondo is how intentional and attentive they are with every child. They consistently call students by name to keep them engaged and focused, model positive behavior through clear examples, and offer meaningful praise and encouragement that builds both confidence and accountability in the children. Master Sahar is truly exceptional! She has an extraordinary ability to connect with children and capture their attention through positivity and encouragement. Rather than focusing on negative behavior, she reinforces good choices and models expectations in a way children immediately understand. The students genuinely want to succeed under her guidance, and it is remarkable how quickly they become more attentive, respectful, and confident in her classes. Miss Joy is equally outstanding - attentive, uplifting, and incredibly knowledgeable. She takes the time to ensure students learn proper technique correctly and thoughtfully refines movements with patience and precision. Master Kim leads with expertise, attentiveness, and high standards. He notices everything, maintains strong discipline, and motivates students to perform at their very best while still making them feel supported and encouraged. We deeply appreciate him and the incredible community he has built. We recently hosted a birthday party at Ji Sung Taekwondo, and it was one of the best decisions we could have made. Master Sahar, Miss Joy, and Esther exceeded every expectation and completely impressed both the children and parents in attendance. Within just an hour, the kids learned technique, discipline, and respect - and by the end of the party, each child successfully broke their own wooden board. It was such a meaningful confidence-building experience, and the children left feeling proud, empowered, and excited. When our children attended their first trial class, my four-year-old daughter was extremely shy and hesitant to leave my arms or step onto the mat independently. By the very next class, she confidently ran onto the mat on her own, and at home she now responds to my requests with, "Yes, ma'am!" every single time. It is absolutely adorable and makes me incredibly proud. That transformation is entirely thanks to the warmth, encouragement, and patience shown by Master Sahar and Miss Joy, along with Master Kim's supportive guidance for parents. Thank you to the entire Ji Sung team for the extraordinary energy, heart, and dedication you pour into every class. Your positivity, teamwork, perseverance, and kindness create an environment that truly shapes children for the better. This is far more than a taekwondo studio - it is a community that inspires children to become stronger, more confident, and more respectful versions of themselves.

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!
