BMAC Stories

Christopher Oses began training at BMAC in sixth grade, where martial arts became a foundation for discipline, family, and purpose. After years away, his career as a Malden police officer led him back to training, recognizing Brazilian jiu-jitsu as essential for fitness, control, and safer policing. Welcomed home by Sensei Marcelo, Christopher now trains with renewed purpose, advocating martial arts as a way for officers to protect others—and return home safely.

BMAC athletes brought heart and hustle to NAGA Boston on June 14! Caleb DeSouza, Peter Krom, and Adrian Duran all took home gold in their divisions, with Adrian also earning a bronze in No-Gi.

Nathaniel grew up in the Mystic Projects of Somerville, getting into trouble and chasing attention. But one day, picking up his sister from karate class, he discovered something that changed everything. He trained hard, earned his black belt by 16, won a world championship, and competed in nearly 80 tournaments. Today, he’s thriving—all thanks to the lessons he learned at BMAC. This is the power of martial arts. This is what we do.

Orlando came to BMAC shy and withdrawn, unsure of himself and hesitant to engage. Through steady training and encouragement, he gained confidence, found his voice, and grew into a leader.

If your child is struggling, we’re here to help them take that first step toward healing and hope.
