Our Story

A Journey Built on Purpose

Calvert MMA Academy began with a simple mission: teach real martial arts that help people.

Founder Jim Thrift first discovered Brazilian Jiu-Jitsu in 1993 through friends training with the Gracie family. When Royce Gracie shocked the world at the first UFC, Jim recognized something powerful — a martial art that allowed smaller individuals to defend themselves against larger opponents using technique instead of strength.

In 1995, Jim met Grandmaster Relson Gracie in Hawaii. Relson was known throughout the Gracie family for preserving the practical self-defense roots of Brazilian Jiu-Jitsu.

That philosophy stuck.

Jim continued training across the United States and Brazil, including time with Hélio Gracie and other members of the Gracie family, while balancing a demanding career in Washington, D.C.

In 1999, Jim began training closely with Scott Devine, a senior Relson Gracie brown belt who had recently moved from Hawaii to Maryland to join the United States Secret Service Uniformed Division.

At that time, non-Brazilian black belts were extremely rare in the United States. Devine became Jim’s senior training partner and mentor, and they trained wherever they could — including Scott’s house and the Secret Service Academy.

When Devine left the area in the mid-2000s, the local training community lost one of its most experienced instructors.

That moment helped spark the creation of something new.

In 2007, Jim Thrift, Matt Almborg, and Toney Waldecker opened Calvert MMA Academy®, Southern Maryland’s first certified Relson Gracie Jiu-Jitsu academy.

From the beginning, the goal wasn’t to be the loudest martial arts school.

The goal was to be the most authentic.

A place where families could train together and build something lasting.
