Chelsea SBG BJJ MMA Portland

“Love this place! I’m very new to Martial arts of any kind. At the time I was so scared and overwhelmed by all of the choices. I had my orientation which helped me decide where to start. I can’t say enough about the atmosphere. Such a vast group of people all striving to thrive not only physically but emotionally, spiritually and mentally. All helping lift each other up.
– Chelsea P.

Patrick SBG BJJ MMA Portland

“Go here if you want to learn the right way. SBG is as encouraging as it is challenging. This is important in order for you to grow as a fighter. I have been a member at other gyms and it was so ego-driven. You will not find that at SBG. Instead, you will find a supportive community that helps you to get to the next level in your training.”
– Patrick D.

“Where Sbg shines is the curriculum and the way they teach the material. Coaches are friendly and make you feel welcome. There are a lot of skilled upper belts and members that have been training there for many years. If you want to train jiu jitsu this is the place to go.”
– Denis D.

SBG Is More Than Just Martial Arts

SBG began over twenty years ago, when its founder, Matt Thornton, opened the first locations in Portland Oregon. His goal was to create a university of fighting, where the truth of what does and does not work could be explored – an academy where ‘best practices’ could develop – where form would follow function.

Since that time, the organization has grown exponentially. SBG now has over 50 locations around the world, and can be found on every continent. It has produced multiple UFC fighters (including the biggest UFC Champion in history, Conor McGregor) – multiple BJJ world champions, including black belt medalists – and currently stands as the world’s leading organization for functional martial arts, combat sports, law enforcement, military hand-to-hand, and self-defense.

In addition to a consolidated business structure and curricula – there is a strong bond of shared philosophy, and loyalty, that unites all of the SBG locations. It is reflected in the organizations motto –

One Tribe – One Vibe.


SBG Portland is also extremely proud to be one of the few academies to be recognized by Rickson Gracie’s Jiu Jitsu Global Federation.

Salóme Ás Thornton

I’ve dabbled in BJJ since 2005, where I first met my husband Matt Thornton in Iceland for a seminar. Yoga; I have practiced since I was 10 years old, so 23 years now. I became a certified teacher in 2010 and started Primate Yoga ~ Practical Practice. Honestly though, my true love for movement is derived from dancing and an insatiable quest for understanding body mechanics. My approach to teaching is informative, playful and challenging. My goal is to give people tools to take care of their bodies, motivate them to work hard and not be afraid to fail.
