I've known Master Kim for almost 20 years now. I was a student at Dae Han when they used to be in…read morethe same shopping center as the Safeway on Contra Costa where Nation's is. I started taekwondo in middle school because I was an angry teenager who had a lot of pent up anger and didn't know how to channel or process my emotions. I stopped shortly before I started high school, because I wanted to play football in high school. Recently, I made the decision that I wanted to come back and earn my black belt and to lose weight. I've struggled with my weight my entire life, and I decided to make some changes, and when I was making the decisions on what my weight loss plan would look like, I decided that I wanted to restart taekwondo as part of my goals. It also helped that in the years between the time I stopped doing taekwondo to when I came back, I would run into Master Kim randomly around the community, from shopping at Costco, having dinner with friends, and whatever else, I always saw Master Kim in and around the community, so it helped us stay in touch If you're a parent with little kids and you're thinking about signing your kids up here, I hope you do. If you're an adult and you're thinking about signing up here, I hope you do. The teens and adults class (middle school and older) is directly after the kids classes. Whenever I hear Master Kim coaching up and encouraging the students, he uses the same gentleness and empowering techniques as 20 years ago. I looked at some of the other reviews from years past, and if you take the time to read some of them, you'll see the same thing from different parents, "My kid couldn't be more excited about coming to Dae Han after school" this, or "My kid's confidence has increased tenfold, a hundredfold," that. Coming back for me has been coming back to the same, positive environment that I left all those years ago, and I'm glad to be back. There's a culture here that Master Kim and Mrs. Kim worked hard to instill, and whether you're a parent or student, you'll see the difference it makes. For the other instructors, they're fantastic. I know and remember Mr. Konstantin from when he was also a student here from my first time here as a middle schooler. Himself, Master Josh, Master Edell, Mr. Nolan, Mr. Hayden, and Ms. Victoria are outstanding teachers who love what they do here. I can't speak to the other black belts, but in my limited interactions with them, they're also good communicators and great stewards and representatives of the values of taekwondo that taekwondo wants to instill in everyone who studies it. I'm glad to be back with Dae Han, and I look forward to seeing where the rest of the journey takes me.

My motto: "Being in shape requires one thing: hard work. And working hard requires no talent" About 4 weeks ago I attended my first class. I was feeling nervous. I had heard crossfit is a hardcore fitness challenge. I walked in with butterflies in my stomach not knowing what to expect. I was first greeted by Meg which runs the gym and who also is a certified crossfit trainer & a has a black belt in Kempo Karate. I still did not know what to expect, and was feeling intimidated by the "WOD" aka work out of the day. I had never done a overhead, power push, jerk before. (scared) Once the class was instructed what we had to do, I was guided by Meg on body mechanics and BAM!! I fell into the swing of it. From my first day experience, it has me coming back four times a week. Everybody is very friendly and welcoming. I remember someone telling me "we all been in your place before", and it only gets better =) Everyday is a new work out so never a dull moment. ***Shouts out to Meg, Alex, Jonathan, Vanessa, and Manolo they all have the drive to provide direction, supervision, encourage, dedication, and motivation enabling you to work safely at your full potential.

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.
