Silicon Valley BJJ Club - Sunnyvale, California

Joining Silicon Valley BJJ was like finding the secret level in a video game—unexpected and totally awesome. The team is like a family that wants to see you level up, whether you’re competing or just working on your fitness. Diego’s knowledge is so extensive, he’s basically the Yoda of BJJ, and he teaches in a way that even a sleep-deprived zombie could understand.

I have trained under Diego for a little over 5 years and I recommend anyone reading this come in and try a class. Their are levels to jiu jitsu and Diego Herzog is at the top in both his own competition career as well as coaching his competition team. If you want to compete or just want to train casually this is the spot. We are a family and would be happy to have you on our team. Children, teens and adults both gi and no gi.

One of the best decisions iv ever made was joining and studying under Diego Herzog’s BJJ. The team feels like a family that only wants to see you succeed, whether it’s for competing or personal training. Diego’s knowledge on the art is so vast and profound, he is easily able to share his teachings in a way that is very understandable and retainable.

Diego Herzog is a great professor and person! It can be intimidating training BJJ as a woman since it’s generally a male dominated sport but I’ve been training for years now under Diego and I wouldn’t have it any other way, I always feel comfortable and empowered after every class!! Come train with us, it’s a great community, amazing workout and you’ll not learn self defense but the best of all martial arts !

I cannot recommend this gym enough. Diego Herzog's passion for the sport is contagious and he exudes mastery in skill and instruction. I brought my daughter here 5 months ago and in that time I've seen her grow as a grappler and as a person. She has caught the bug and if we weren't moving, I'd have her in this gym for as long as possible. I also joined for about a month but got a minor foot injury and wimped out, but in that time I felt nothing but welcomed and encouraged.

This is not one of those places that teaches your kids to yell in unison. This is not one of those places that hands out belts. This is a gym of real Brazilian Jiu Jitsu and is ran and attended by people who love the sport. Very sad I have to move, it will be hard to find a place as awesome as this.

I signed up for a Muay Thai class with Coach Diego and have to say it’s the most amazing class ever. He is passionate and patient with new learners. I’ve improved a lot of movements since joining his Muay Thai class. He also provides group classes and private classes. His technique is precise and easy to learn step by step. You feel welcome in the groups and everyone is friendly in the class. His class makes you feel like you don’t want to skip, always look forward to the next sessions.

Diego is an amazing teacher and person. He competes at the highest level of BJJ and MMA and his confidence in teaching is second to none. He has a very chill attitude with students and is great for both beginners and advanced students. Thank you for all you do Diego!

If you want to learn Brazilian Jiu Jitsu from the world class expert – you’re in the right place. I’ve known Diego for about 7-8 years. I consider myself of being a lucky man because I’ve got such a knowledgeable, experienced, smart and technical Coach. And he is a very nice and kind guy as well.
Teammates are friendly and there is a pleasant vibe there overall.
To make long story short, it is the fun and tough sport that we love. And Diego is helping us to improve and enjoy this long (hopefully life-time) journey called Brazilian Jiu Jitsu!
