Who We Are
Grizzley Den Jiu-Jitsu Academy
Our School
This is much more than a Jiu-Jitsu academy – we’re here to maximize your experience. Our Jiu-Jitsu classes are high-paced sessions that feel more like seminars than walk-throughs. This ensures we follow “The Grizzley Way!” We find different strategies in and out of martial arts and develop them with each student’s individual style. It’s not about you being perfect for us; we want you to be perfect for you! And we want you to know it’s never too late to start! Isaiah’s experience speaks for it. By starting Jiu-Jitsu as an adult, and becoming a brown belt in 4 years and 7 months, he shows that anything is possible. You can have a similar experience to reach your life goals no matter where you are in life by joining us at Grizzley Den Jiu-Jitsu Academy!
History
Isaiah “Grizzley” Riley first opened a Jiu-Jitsu studio in 2024. This gave him a foundational experience to develop his teaching style and continue to improve his skill set. Now at Grizzley Den Jiu-Jitsu Academy, Isaiah is setting students up for success in and out of the academy.
Before ever stepping on the mat, Isaiah spent 15+ years in the Marine Corps, including service as a Drill Instructor. The experience was a huge turnaround for him! He witnessed the impact he could make on young people to improve their discipline, mental toughness, and leadership abilities. This has become an instrumental part of our mission to build the next generation of leaders and competitors. We are invested in your journey!
After his years of service, Isaiah’s journey in Jiu-Jitsu began in 2020. And he thrived immediately. Isaiah has grown quickly in Jiu-Jitsu, filling his trophy case, including 3 IBJJF Pan Gold Medals (Gi/No-Gi) (White, Blue, Brown Belt), Fight2Win 281 Brown Belt Ultra Heavyweight Champion, and more accomplishments. He used different tactics from life, sports, and other martial arts to propel his progression.
Isaiah is dedicated to passing down all his experiences and perspectives to change lives through Jiu-Jitsu in Stafford!
