Adam Linn

This where Adam’s MMA foundation comes from.  While in the Netherlands, Adam started coaching and competed in the European submission grappling circuit. He is trained in the Dutch style Kickboxing and Mixed Martial Arts.

Adam holds a Bachelor’s degree in Healthy Lifestyles Coaching through Arizona State University and carried a Personal Trainer certification through the National Council on Strength and Fitness (NCSF).

Adam is an approachable instructor who meets his students where they are and helps them achieve their specific goals at their own pace. He strongly believes in keeping a, “SAFE, CLEAN and PLAYFUL environment where individuals can make mistakes and grow as people and martial artists.” Adam says, “We check our pride and aggression at the door and together help each other become better versions of ourselves.”

This quote from Bruce Lee captures the essence of Adam Linn’s training methodology:
“Knowing is not enough, we must apply. Willing is not enough, we must do. Adapt what is useful, reject what is useless, and add what is specifically your own.” -Bruce Lee

Dusty Hjelle

Dusty Hjelle is a purple belt under Rob Biernacki and has been training and competing in JiuJitsu for over 12 years. Dusty first learned JiuJitsu for MMA, but after sometime, realized that his true passion was for the art and sport of grappling. 

Over the last couple of years, that passion has grown past just learning and competing, but to teach and grow the art in the greater Twin Ports area. 

Dusty is passionate about JiuJitsu not just as an art, but as a means to a community where you can find belonging, develop skills and gain confidence for life. It’s Dusty’s mission to teach JiuJitsu through a science based approach of understanding “base, posture, structure”, or as his coach Rob calls it, the, “alignment theory.”
