Rooted in martial arts.
Built around people.
Experienced coaching, thoughtful training, and teammates who want to see you improve. At Dominion BJJ, you have a place to learn, challenge yourself, and belong.
Good training starts with trust.
Our academy brings people together through Brazilian Jiu-Jitsu, Judo, and Muay Thai. Some arrive looking for fitness or self-defense. Others want to compete, return to training, or try something completely new.
Whatever brings you through the door, our focus is the same: help you learn, get stronger, and build lasting connections with the people you train alongside.
Coaching that makes sense
Clear explanations and practical fundamentals give you a foundation to build on, with technical depth to keep experienced students growing.
Respect on the mats
Training asks us to trust one another. We value considerate partners, honest effort, and a room where people from different backgrounds feel welcome.
Progress at your pace
You do not need experience to get started. Bring your questions and your willingness to learn; we will help you take the next step.
Our roots in Brazilian Jiu-Jitsu.
Dave Trader began training Brazilian Jiu-Jitsu with Leo Dalla in 1996. He earned his blue belt and competed in several major tournaments before Dalla returned to Brazil.
Dave continued training with fellow Dalla student Lloyd Irvin, who awarded him his purple and brown belts. During that time, Dave also earned tournament victories in both Brazilian Jiu-Jitsu and Judo.
After time away due to injury, Dave returned to train with Dalla and received his BJJ black belt in 2005.
Dave is known for a well-rounded game: strong throws and takedowns, heavy pressure from top position, skillful submissions from the bottom, and a guard that is exceptionally difficult to pass.


A welcoming place to learn and grow.
Dominion BJJ is more than a Brazilian Jiu-Jitsu school. Our focus is to create a welcoming environment where students can learn, improve their health, and build lasting bonds.
We value a close-knit, family atmosphere where new and longtime students can connect. The trust involved in training together creates unique friendships, often between people who might never otherwise have met.
People of every race, religion, age, and gender are welcome on our mats. What brings us together is respect, shared effort, and a willingness to learn.
Experienced instruction. Room to keep improving.
Our Brazilian Jiu-Jitsu classes are taught by third-degree black belt Bill Nagle. His distinctive instructional approach offers insight for both new and experienced students.
Bill combines expert instruction in BJJ fundamentals with current competition techniques, training methods, and innovations, helping students build a strong foundation and continue developing their skills.
Big goals. The same commitment to our students.
Our long-term goal is global domination. Just kidding! We do have big plans for Dominion BJJ: a stronger competition team, more teammates on the podium at the highest levels, and a school and community that continue to grow.
We will keep building on our technical background, experienced instructors, and approach to training to give students an outstanding learning environment.
Our promise is to stay dedicated and motivated, continually raising the standard of Brazilian Jiu-Jitsu training and helping our students reach their potential.
