Whether you’re looking to compete, get in shape, or just ready for something new and exciting, “The Lair” provides a professional, yet family-friendly atmosphere, specializing in Brazilian Jiu-Jitsu, kickboxing, and wrestling for children and adults. Our mission is to empower our students by helping them develop and improve both physically, and mentally through their progression in martial arts, leaving them confident in their self-defense as well as the ability to dominate our competitors in competition.


The Grapplers Lair has a long and impressive history owed to its founders, John and Susane Moore. John is a 2nd Degree Black Belt under Shawn Hammons of Nashville, Tennessee. He began his martial arts quest at the young age of 8 years old. After meeting his wife, former bodybuilder, Susane Moore, they decided to join forces and build a legacy whose reputation would extend throughout the United States. From producing multiple professional athletes, who have made names for themselves in top MMA organizations (including UFC, Bellator, Strikeforce, and World Series of Fighting), to leading the Ft. Hood. Army Combatives Team to victory, this power couple has most definitely made their mark in the martial arts community.
