One Jiu Jitsu 544 East 1st Street, Tustin, CA 92780

"Great Home gym, amazing teachers, great people to train with :)"

"My child attend this studio, so this is a perspective of a parent. Professor Mo is so gentle and patient with children. There are regularly 6 instructors, with typically 4 black belts and blue or above. My child has really grown in the sevaral months we've been here. I looked at several studios and disciplines and the most pointed to here. It does get crowded, but with so many instructors, every child gets attention. The youth class is broken into 2 sections, 1 for learners, that my child is in. The other side is more advanced and these kids are legit. I encourage any parent in the area to give this studio a try. Also, with kids that have kids that may have difficulty trying new things, the instructors are so encouraging. I really wish I had this kind of environment when I was younger."

"I can’t say enough about how great One Jujitsu is. This is the best gym you will find. Go to the class you will see the way they teach the class you can tell that they care and want to help you improve. It’s very clean and everyone is really cool! There are many gyms a lot closer to where I live. This one is worth the drive."

"I traveled here for the women’s bjj camp last year and had an awesome time. There’s a great community of women at the gym who build each other up and support each other’s progress, and it was amazing to be a part of this for the weekend. There were some world class black belts teaching who were excited to share their knowledge and help us improve. Giva and his family are great people. Definitely check them out if you’re in the area."

"I take my almost 7 year old here, she loves it! Class size is almost 30 kids, class says for 30 mins but goes on for about 40-45 mins, we love it. They know her name, they teach her wrestling , what kid wouldn’t like it?"
