🥋 ONE MAT. ONE COMMUNITY.

Last night was a great reminder of what Brazilian Jiu-Jitsu is really about — community, growth, and bringing people together through a shared love of the art.

We’re proud to officially welcome Marcello to the 20,000 Leagues Jiu Jitsu family. Marcello brings decades of experience as a 3rd-degree black belt, along with a talented group of competition athletes who joined us on the mats last night for a combined Open Mat.

Different backgrounds. Different teams. Different levels of experience. But when we step onto the mats together, we’re all there for the same reason — to train, learn, challenge each other, and get better.

This is exactly the type of environment we want to continue building at 20,000 Leagues: hard training, mutual respect, no egos, and a strong sense of community.

Thank you to everyone who came out, welcomed our new teammates, shared rounds, and made it such a great night.

We’re excited to have Marcello and his crew with us, and even more excited about what we’re building together.

The future at 20,000 Leagues is looking strong. ⚓️🥋
