Who We Are

Our vision is to offer accessible and world-class training to people of all ages, sizes, genders, and backgrounds in the multiple athletic programs offered. We serve not only athletes, but anybody looking to learn new skills, get in shape, have fun, and join our community.

Welcoming & Competitive

Bay Jiu-Jitsu was created out of a strong passion, a shared vision and a ceaseless commitment to making martial arts learning easy and accessible to all people. Since opening in 2008, we’ve had the opportunity to work with countless students as they acquired foundational skills, developed new techniques and confidently moved forward in their learning journey. Known as one of the most welcoming and competitive Martial Arts School in the San Francisco Bay area, we provide a wide range of classes to support students from all backgrounds and levels. Our jiu-jitsu team participates in local, state, national, and international tournaments, but many of our members practice for the sake of fun, fitness, and overall self-defense. We welcome all motivated people with an atmosphere of inclusivity while providing top-notch instruction.

Flexible Pricing

Versatility is key. We love to give our students options of payment because every situation is different. Ask us about our discounts for teachers, first responders, full-time students and low-income families.

Bay Jiu-Jitsu's Core Values

What drives us everyday

Bay Jiu-Jitsu exists to provide people with the tools and training they need to build confidence and strength in all aspects of their lives. We do this through martial arts and fitness classes, online content, products, events, and community that challenge our students to push beyond their comfort zone and overcome physical, mental, and emotional challenges.


Bay Jiu-Jitsu is built around five core values, and they are the foundations of our culture.



We know that discomfort accelerates our growth. We get out of our own way. We embrace challenging situations that make us stronger. We don’t fear failure, we learn from it. We make moves, not excuses. We understand quitting is not an option.



We are open-minded when it comes to new ways of approaching problems and jump at the opportunity to learn from others. We welcome constructive feedback and grow from it. We challenge the status quo by seeking clarity and asking questions. We know that what got us here won’t get us there.



We believe in our core that we are changing our lives and the lives of our training partners. We wake up every morning ready to be the best and give the best version of ourselves to our community. If a teammate needs help, we step up to the plate and help them. If we notice a problem in the gym, we take action to make sure it gets resolved.



We welcome a friendly training environment to anyone regardless of sexual orientation, gender identity, or race. We are each other’s biggest cheerleaders. We work well with others, communicate directly and respectfully, and set clear expectations. We are positive, optimistic, and bring each other up.


We are committed to living our best lives as a whole. We train consistently, take care of our bodies and minds, and live true to our own personal values. Our discipline, commitment, and tenacity translates into our daily lives outside of the gym. When life pulls us down, we stand up and get right back at it.

About Stephan, Bay Jiu-Jitsu Founder

When I was a kid, I wanted to be a ninja when I grew up. I debated starting my ninja career in either martial arts or gymnastics. Since backflips would be a critical ninja skill to develop, gymnastics was the way to go. Once in college, I settled on the next best career to ninjahood - an elementary school teacher. While studying full-time, I worked three jobs to pay for my tuition and continued dabbling in my ninja hobbies. I tried many martial art styles (Aikido, Krav Maga, Arnis, Jeet Kune Do), but most did not have opportunities to compete. For me, competition is the best way to measure my skill progression and know if I'm getting better at something. I first discovered Brazilian Jiu-Jitsu in Santa Cruz and immediately fell in love with it. Unlike all the other martial art styles I tried, I could compete in jiu-jitsu, measure my skill progression, and ensure my techniques worked in high-pressure situations.


I trained jiu-jitsu for two years in college in Santa Cruz, competed in about dozens of white belt tournaments, and earned my blue belt by graduation. Afterward, I moved to the Bay Area and started my first job as an Oakland Public School teacher. At the same time, I was training and coaching adults and kids jiu-jitsu and gymnastics at a few gyms in the East Bay. After six years of teaching as an elementary school teacher, I decided to focus on coaching jiu-jitsu full-time. I competed in every jiu-jitsu tournament I could and worked my way up to my brown belt. In 2010, I earned my black belt after winning five gold medals as a brown belt. Then I opened the first Bay Jiu-Jitsu permanent location in Japantown. Our student community multiplied, allowing us to grow our gym to 4 locations throughout the Bay Area over the next ten years. Since then I’ve competed and medaled in dozens of tournaments including winning gold for the USA in the Veterans 2016 Combat Wrestling World Championships in Hungary and placing second the following year in Japan.


Then COVID hit in 2020, and we had to stop all in-person classes. It was a challenging year for everyone, forcing us to close 3 of our 4 Bay Jiu-Jitsu gyms. But our students didn't want to stop learning, and I knew I couldn't stop teaching, so we continued classes on Zoom and YouTube train-at-home videos.


Now I'm happy to say that we are back in the Japantown gym and fully operational. I am so grateful to the Bay Jiu-Jitsu students who stuck with us throughout our Zoom days and to all the new people who have joined our community over the last few years. Throughout the ups and downs, coaching and developing students in their physical skills and confident mindsets have kept me going. It's the drive behind why I do what I do every day. The sport of jiu-jitsu and the Bay Jiu-Jitsu family transformed my life, and I'd love to share it with you.
