I am a super newbie to martial arts and really feel I found the best martial arts gym in the Bay Area. I initially wanted my son to do the classes and after watching the coaches and seeing their style, their enthusiasm, their love of the sport, and how patient they are, I had to join the adult class! First the kids classes are hands-down the best I’ve ever seen and then when I started doing the adult class I really was welcomed and never felt intimidated. 💕

The PSD is fantastic environment for learning with an excellent group of instructors whether you're looking to train hard and improve your skill set for a competition, for practical use like law enforcement, or even if you're an older weekend warrior like myself just trying to lose a few pounds and move at your own pace.
The school offers an excellent blend stand-up, as well as ground/grappling programs affiliated with legends Jean Jaques Machado, Eric Paulson, Dan Inosanto:
- Brazilian Jiu-jitsu
- Combat Submission Wrestling
- Kickboxing
- Kali/Escrima
- Jeet Kun Do

Eric is a great instructor. Very humble and loves to teach. He will always respond when you have questions. Our whole family trains here and we haven’t had a disappointment yet. I have recommended this school to most of my colleagues and friends. Family atmosphere for both kids and adult classes.

I started training at PSD in January 2019. Having trained at multiple academies, both in the states and overseas, I can say with confidence that the staff, facilities, instruction, and overall vibe of the gym are top notch.
Whether you're training jiujtisiu for health, fun, or to collect gold medals, you'll find a solid jiujitsiu curriculum for hobbyists and competitors alike here.
10/10 would highly recommend that anyone looking for a gym stop by and get some rolls in.

This is an amazingly warm and welcoming place to train. It's a real community and you feel welcomed from the first moment you walk in the door.
I train in Jiu-Jitsu here and want to be at the gym for every session just because of the family atmosphere and strong community culture.
The instructors show care and compassion for each person and really I cannot express enough the heart that is in everyone here, including fellow gym members.

We take our son here for more than just the great jujitsu training by the talented and technical instructors. Almost as important as the training is his newfound ability to take on difficult situations and get back up, over and over, from what some see as failure, and what he now sees as something he learned. He gets to train against other kids who are more experienced and demonstrate that in a respectful manner, and he has an opportunity to to do the same with newer students. Very few places around that balance teaching humility, building self confidence, and helping us in making him a better

If you like challenging yourself to improve, if you enjoy testing your limits, you will regret not coming here sooner. Very fun. Therapeutic work out. Coach Eric Acha has created a great environment and attracts quality people.

Peninsula Self Defense training academy has far surpassed my expectations as a positive and fun activity for my daughter. She just turned 6 and has been going there for close to a year and absolutely loves it. We go 4 days a week and she never says she doesn't want to go. Her progress is amazing, the kids learn very fast because of the premium instruction given by Eric and his staff (Rony, Yolanda, Aracely and Vianney). My husband also joined the adult class which takes place after the kids class. It sparked his interest very quickly after my daughter joined. Jiu Jitsu quickly became his new passion

Peninsula Self Defense is an excellent school for BJJ. Eric the instructor is one of the most gifted teachers I have ever had the pleasure of taking a class with, he's very detail oriented, has superb technique and is genuinely passionate about helping people get better at BJJ every time you step on the mat. The school has a great family feel to it, kids, dads, mums all come and train together. The school has the largest mat space on the Peninsula, loads of parking, big changing rooms, very conveniently located. Check out the great schedule and go try it out, you will not regret it.

I have trained here for the past couple of years PSD is great. Also, both of my daughters also train Brazilian Jujitsu. Eric Acha is so knowledgeable and technical in Brazilian Jujitsu and a great role model not just on kids but also on adults as well. It's a great place to train, great environment, everyone treats you like family. When you walk in the building, you will feel welcome and you will walk out with an smile on your face. I would recommend PSD any time.
