Nelson is so fantastic!!! Just signed up for 5 more training classes with him after the initial…read moreself defense lesson. I felt more confident within the first 5 minutes learning from him but then he really goes into each position we might be put into and what our options of defense are to get out and attack our attacker! He even pads up and has us practice on him. I am blown away by how little I knew before this class. I would have been useless and I already feel so much stronger and safer after just one 1.5 hr session! Nelson is fabulous. He is the sweetest, most encouraging but straight forward teacher. I could go on and on about how highly I recommend him. You will NOT regret this class (definitely might feel sore after though!!!) My friend and I have been obsessing over our newfound passion in this training and can't wait to continue with Nelson!!

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.

I…read morestumbled upon USSD on Facebook and they were offering two weeks for free and so I decided to check it out. I liked that during the pandemic they taught the classes outside or virtual. Both my son, and now my 5 year old daughter, have been taking classes here for almost a year now. Our first encounter was with Sensei Christine. She is so friendly and easy to talk to, and basically the administrative backbone of this place. Whenever I had a question, schedule change, or whatever, she has always been so accommodating and makes you feel like you a part of a family. My kids absolutely love Sensei Jack! He always makes classes engaging and funny. He is really good with the kids. I like how they not only teach karate, but also the principles of karate and how to deal with every day life situations, like dealing with a bully. I have learned some life lessons myself while watching in on his group classes! The program itself consists of a 30-minute one-on-one with a trainer and then 3 optional 45-minute group classes (based on age). They earn stripes on their belts depending on what they have learned for that particular belt. Once they receive 4 stripes they can test for the next color belt. Tests are usually done once a month. The kids have incentives to earn "ninja dollars" which they can collect to redeem for toys at the "ninja store." The kids really loves this and gives them an opportunity to work harder and be more engaged.

Master Turner is as good with kids as he is with adults, and the other instructors, all of whom he has hand-picked, are also superb. The atmosphere is friendly and welcoming. I've been working out here for 10 years now, and never plan to stop.

One day, I finally gave in to his persistence, attended a trial class, and ended up signing up the very next week. Every day on the mat is a learning experience, and training at Gracie Barra has instilled a strong sense of discipline in me. The professors are incredibly kind and patient. Even if I've practiced a drill countless times and still forget a step, they make sure I feel comfortable and always guide me through it. I genuinely look forward to every class and deeply appreciate the amazing professors and training partners who have become friends along the way. I highly recommend this Gracie Barra location to anyone looking to start Jiu-Jitsu.

I also want to sincerely thank the whole team -- Kody ,Maison, Aubrey, Léo, and Leslie -- for their professionalism, kindness, and constant support.

Today, as a blue belt, I can clearly see how much this place has positively impacted my health, mindset, and lifestyle.
