Fusion MMA & Jiu Jitsu

Fusion MMA & Jiu Jitsu in St. George was built on the idea that serious training and a respectful room go hand in hand. Under the leadership of Master Instructor Aaron Reis—a 5th degree Gracie Jiu Jitsu black belt and black belt under Walt Bayless—the academy has become a place where both new and experienced students can develop real skill and composure. Fusion operates as part of the Fabio Santos BJJ Association, linking its technical standards directly to the legendary Rolls Gracie lineage through Master Fabio Santos, one of the world’s few coral belts and a direct Rickson Gracie black belt. The gym’s programs reflect a belief in structured, honest training. Brazilian Jiu-Jitsu classes are offered in both gi and no-gi formats, with clear fundamentals for beginners and steady progression for returning students. Women’s BJJ and self-defense classes are led by Coach Jennifer Reis, a two-time IBJJF No-Gi Brown Belt World Champion, who has built the region’s strongest women’s program from the ground up. In addition to jiu jitsu, students can cross-train in MMA and Muay Thai, with striking programs led by experienced coaches like Kru Mickee Porritt, whose background includes over 50 Muay Thai fights and multiple championship belts. Open mat sessions and drop-in training are available, giving both locals and travelers a chance to find rounds and test their skills outside structured class time. With dedicated programs for adults, women, and kids, Fusion MMA & Jiu Jitsu offers a training environment where technical standards, consistent effort, and mutual respect set the tone on the mats. The academy is wheelchair accessible and maintains multiple locations in St. George and nearby Mesquite, making it a practical fit for a wide range of students and families.
