ATI is an exceptional studio that defies easy description. Master Kwon is an incredible teacher…read morewith a fierce passion for Taekwondo, both in practice and instruction. He is extremely kind and highly respected. Not only does he teach children about kicking and punching, but he also instills in them the essence of being a true martial artist. At ATI, students are also introduced to Korean culture, the birthplace of Taekwondo, as Master Kwon incorporates it into the learning experience. The instructors here are truly qualified and excellent in both technical and teaching skills. They are certified by Kukkiwon, the headquarters of Taekwondo in Korea, and have achieved numerous accolades in local, regional, national, and international competitions, including prestigious ones like the US Open. They respect the students and teach them with complete dedication. A lot of students are also actively participating in many Taekwondo competitions throughout the year which makes the school such a vibrant and positive environment. Over the years, my little kid has trained here, and I can attest that ATI is a well-known and reliable Taekwondo school in our local community. The studio's inclusion of children with special needs, adults of all ages, and students from diverse backgrounds, including those transferring from other Taekwondo schools, states, and countries, makes it an exceptional place for training. I do not think there are any other Taekwondo schools in the area offer classes for all ages. The closest one is like 15miles away from Garden Grove. One of the most realiable and credible things about this studio as I know is many trainers at ATI have been with the school for many years, starting from their elementary school days and continuing through to graduating from college, whether as engineers or while earning doctoral degrees. A lot of them have established careers and been successful as well. I rarely write reviews on Yelp, but I feel compelled to respond to some of the negative comments. In martial arts, children must learn discipline and respect for others, from family members to strangers. This is a fundamental pillar of ATI's teaching. During belt promotion tests, which occur every 2-3 months, all students are encouraged, though not required, to spend a few extra minutes observing their peers as a way of learning and showing respect. I believe this is an excellent method of educating children on mutual respect. I don't understand the complaints about tuition. My child has trained here for years, and ATI's tuition is among the most reasonable in the area for such high-quality training. I find the negative reviews strange and unfounded. Moreover, ATI is the only Taekwondo school in the area that offers free trials for students. Master Kwon has been teaching and running this school with passion for over twenty years, so I believe the negative reviews are unjustified. Thank you again, Master Kwon, and all the incredible instructors and trainers at ATI.

I had…read moreabsolutely no knowledge of kickboxing, so I thought this would be a place where I could learn from the beginning, especially since I was hoping Nam Phan would guide beginners like me. But honestly, my experience was very bad. I came on a Saturday and arrived about 20 minutes early. When I told him I had never trained in martial arts or kickboxing before, instead of giving me basic guidance, he seemed annoyed that I didn't know anything. Then he told me to warm up by myself. When I came back, there was only one other student there, and that person had only been training for about a month. But the person who actually showed me what to do was that student, not Nam Phan. During training, Nam Phan briefly demonstrated a few moves and then told me to practice with the other student as if I had already been training for a long time. I was a complete beginner, so it was honestly very difficult to keep up. Throughout the entire session, he only corrected me once, but kept yelling loudly at me whenever I made mistakes. I felt extremely uncomfortable but still tried to continue training. Since it was my first class, I also didn't know what I needed to prepare. Before I came, he specifically told me I didn't need to bring anything. But when training started, he suddenly asked if I had boxing gloves. When I said no, he threw the gloves he was holding onto the ground aggressively and asked in an irritated tone why I didn't prepare anything. Throughout the whole session, the way he spoke and his attitude made me feel like I was being scolded for not knowing anything instead of being guided as a beginner. He spoke Vietnamese very quietly and unclearly, so many times I couldn't even understand what he was saying. That training session made me feel extremely bad and uncomfortable. I came in wanting to try and learn a new sport, but instead I only felt pressure and negativity from beginning to end.

You can always tell he loves what he teaches. The students pay a fixed fee. The good thing is they can come as many times during the week as they want to. Sensei Doan explains how each body shift, arm and leg movement, block, strike, kick in each kata can be used in practical ways. He analyzes kata and extracts fighting techniques from the movements of a "form" (kata). My kids get excited to see how they can apply the techniques they learn in the Katas. They look forward to attend these special sessions of the week. One thing I like about this Dojo is all students come here to learn. Sensei Doan always emphasizes how important it is for each student to concentrate on the lessons and improve his or her techniques to the next level. He teaches his students to respect themselves to earn the respect from others. As they achieve each level of the belt rank , they improve not only their Karate techniques but also develop their personal characters accordingly. We believe this dojo is one of the top notch Karate dojos in this local area. If you are serious about learning Karate or Self Defense techniques, we definitely recommend you to check out this Japan Martial Arts Center (Japan Karate-Do Judo Jujitsu). You wont be disappointed!

I have been a hobbyist of various martial arts for years. Since day 1, the environment at Rounders was a perfect fit. The people are friendly and helpful. The hours and the selection of martial arts classes are excellent. Every last coach knows their stuff, and they teach both kids and adults classes with professionalism and care. I am also always grateful that the black belts, pro fighters, and other experienced trainees are so helpful during class. Not only do you have knowledgable coaches, but your peers support you here too. I have seen multiple martial arts gyms over the years, especially in Orange County, and while all have nice things to say about them, Rounders just hits every single mark. It's a nice and spacious facility with a great setup, but the people are what make it stand out. My only complaint is that I wish I had started here sooner.

They are completely invested in your success, and will continually challenge you, because they care enough to ensure that you are prepared to handle any situation on the street. I really like Yuri, Gal, Jonathan (Asian guy), the two Asian ladies (Jackie & ing? they are tough as nails, sorry can't remember all names). Big shout out to ownership and everyone involved in Krav Maga OC for their guidance, support, and inspiration! I've been into self defense since I can remember. I have my guns, my knives, etc... that said, l needed to learn Krav Maga... ESPECIALLY during these unfortunately CRAZY TIMES as antisemitism is at an all time high. This little Jewish lady was not raised to be a victim! Anyhow, i have been practicing defending with knives at home, spend quite a bit of time shooting at the range, etc... but having the tools and skills stated above would be more beneficial with some Krav Maga training... being attacked on the street is a completely different experience when you're dealing with an attacker in real life than in a controlled environment. I want to be prepared just in case G-D forbid I have to implement these techniques in real life. I truly look forward to learning more and refining my skills. That being said, I highly recommend Krav Maga OC. Yuri, his team, and those who are in my classes continue to impress me with their deep reservoir of knowledge and talent. Todah Rabah!
