Michael Jalen Fonacier Biography

Michael Jalen Fonacier was born on August 9, 2005, in Los Angeles, California, where he was raised.

As a toddler, Jalen followed his father and uncle to the local jiu-jitsu academy, who noticed how Fonacier always paid close attention to what was going on in the class. Although the kids’ class didn’t have any children in his age range, they signed him up for the class.

Starting at age 2, under Rey Diogo at the Carlson Gracie Academy affiliate in Los Angeles, Jalen Fonacier became increasingly invested in the sport. By the time he was a yellow belt, his desire to compete pushed him to look for a team with a stronger representation in the tournament circuit, which he found at team Alliance LA, coach Rubens Charles’s Cobrinha‘s workgroup.

Jalen Fonacier went from his yellow belt to the black belt rank – earned in May 31, 2024 – while earning many important IBJJF titles along the way there and gaining recognition as one of the sport’s hottest prospects.
