Black belt · Coaching · Defensive tactics

Will Brooks

Will is a jiu jitsu black belt under Professor Michael Estrada, as well as a coach, competitor, and jiu jitsu content creator. He began wrestling at age 14 and has trained jiu jitsu since 2015, earning tournament medals along the way.

Will has trained around the world, including Puerto Rico, Switzerland, Canada, and Mexico, with his sights set on Brazil and Japan next.

For the past decade, Will has remained certified and active in defensive tactics for law enforcement. His Level 2 Gracie Survival Tactics (GST) certification further qualifies him to teach jiu jitsu to police and military personnel. After undergoing a cervical spine fusion, Will returned to the mat—an experience that shapes his resilient, technically focused, and welcoming approach to students at every level.
