I have trained here since 2005 and can't say enough good things about the academy or the people there. The head instructor, William Diaz, is a very caring and incredible teacher. You will get fantastic instructions from a highly skilled and respected black belt instructor. He keeps the place safe and upbeat. The students are friendly and humble. There are no egos here and everyone helps each other to improve. The academy is like a family. Whether you live in the Mountain View area or just visiting, come down and check this place out for yourself. You won't be disappointed!

Ralph Gracie Jim Jitsu is a great school with some really talented, hard working people. The gym is very clean and inviting. I was having a hard time finding a place that fit after moving here from Chicago. I called and was invited to drop in and check out a class for free, so I stopped by in one evening and loved it. Everyone is very accomodating to your skill level. The school has great instructors and makes sure to not make you feel out of place or intimidated when you first start out. A couple of months before COVID I decided to enroll my 10 year old daughter. The classes has already taught her flexibility, control, discipline and respect along with the fundamentals of jiu-jitsu She is super excited and looking forward to go to class and the best part learning how to protect herself. We are both patient looking forward to getting back in the gym.

I have trained at the Ralph Gracie academy in the peninsula and South Bay for nearly five years. I started as a noob white belt and am now a purple belt. The instructors, and fellow students have provided a challenging, safe, and welcoming environment to grow into the practice of Jiu-Jitsu. The journey is not easy, but is very rewarding. The instructors at the academy include head instructor, Justin "Machine" Holder, Dorian "D" Cartwright, and Darren "Chef" Ogasawara. The standard of instruction is high with emphasis on solid and consistent fundamentals, sustainable practice, self-defense, and practical execution. The community at the academy are welcoming and hard working, which are essential to learning and getting better. If you are a competitor, hobbyist, have fitness goals, or want a more interesting experience than the gym check out our two locations in San Jose and Santa Clara.

I am totally satisfied with their Kick Boxing class! I started joining the class when I came to Santa Clara, one and half years ago. At that time I just take the class as drop-in member but I sifted to monthly membership because the class was pretty nice, useful, and fun! Especially trainers are pretty good and kind for both beginners and experienced people. Now I take 3 times a week after finishing daily works. I recommend you to join for physical and mental health. Average people who join a class are 10 and now increasing. Women are more than 40 %. The monthly fee has been lowered, making it easier to participate!

My boys have been going to RGSJ for about a year now, and the instructors and community there have really helped my boys with their self confidence. They have a sense of belonging along with learning that the disciplines they are taught are not just for the academy but also for whatever they encounter in life. My 6 year old has learned to focus better in school, and has gained so much self discipline since he has started. The coaches show and practice what it means to not only be physically strong, but also mentally strong. It is nice to see that this is not only a family friendly environment, but also the care the coaches bring really emphasize how much they want their students to be well rounded individuals.

Experienced instructors focused on providing quality training for children and adults. The academy has a very respectful atmosphere. My family and I really enjoy rolling here as well as the Santa Clara site.

I travel a lot, and have been to many BJJ gyms (good and bad), and consider myself fortunate to have found a home here. They are a friendly, and helpful bunch. The head instructor Justin ‘Machine’ Holder has been training under Ralph Gracie since time eternal, and has done a fantastic job of instilling in us the fundamentals of Gracie Brazilian Jiu-Jitsu while still addressing the newer generations of ‘the game’.

From the moment I walked in the door the first time, the instructors were enthusiastic, professional, and welcoming. The last year and a half I feel like I gained a second home and family. Cant say enough good things about the instructors, students, and establishment!

I enjoy training here. The instructors are great and the atmosphere is welcoming to new people. Higher belts have been very helpful and patient with me while rolling. Highly Recommended.

The professors and more experienced members are very welcoming to new people and give helpful pointers. Instruction is excellent, I've only been here a few months and I can tell I'm learning and improving. Also they have a great Black Friday sale on the year-long membership, so November is a great time to join!

My son (8) joined about 2 months ago. The teachers are really great with kids. They are patient with kids, but try to instill some discipline as well. My son's confidence has gone up, and he looks forward to his 2 visits a week, to the dojo.
