About Us – Gym Jitsu Allen

At Gym Jitsu Allen, we believe Brazilian Jiu-Jitsu is more than a sport—it’s a path to becoming a stronger, more grounded version of yourself. Founded by Kayvon Rahbar, our academy was built to bring the life-changing power of martial arts to everyone, delivered with authenticity, excellence, and heart.

Our Story

The journey starts with Kayvon. After being laid off from his real estate development job, he spent over 18 months searching for work—40 pounds overweight and searching for purpose. A former high-school wrestler and college football player, he walked into a BJJ academy because it felt familiar. What began as a way to get back into shape became a passion—and then an obsession.

Gym Jitsu Allen is the realization of his lifelong dream to build a mission-driven, community-focused business. By his side are his wife, Clarisse, and their two young children—Rose (2½) and Rocco (8 months)—whose energy fuels our family-owned academy every day.

As a local business rooted in Allen, Texas, our mission is simple and unwavering: help every student become better—mentally, physically, emotionally, and morally—through the discipline and community of Brazilian Jiu-Jitsu.
