Coach Chad Mertens

Head Striking/MMA Coach

A proud graduate of CGHS and accomplished former professional MMA fighter, he brings extensive combat sports expertise with 19 combined amateur and professional bouts to his credit. His martial arts journey began in the summer of 2010, leading to a remarkable milestone in 2013 when, at just 19 years old, he became the youngest professional MMA fighter to emerge from Lane or Douglas County—a distinction earned through unwavering dedication and genuine passion for the sport.

Throughout his competitive career, he has competed across six states and trained with elite athletes nationwide, including multiple UFC world champions and dozens of world-class competitors. This comprehensive experience has provided him with invaluable insight into the disciplines and strategies required for success at every level of combat sports.

He holds the rank of Brazilian Jiu-Jitsu purple belt under Master Fabiano Scherner, a 5th-degree BJJ black belt, UFC veteran, world-class practitioner, accomplished coach, and founder of Chess Lab BJJ.

Leveraging his diverse background in MMA, Boxing, Muay Thai, wrestling, and Brazilian Jiu-Jitsu, Coach Chad specializes in teaching practical self-defense skills while fostering discipline and confidence in students of all ages.

Beyond his professional achievements, he is a devoted husband and father to one son. His mission is to enrich his community by empowering others to develop strength—physically, mentally, and emotionally—through the transformative practice of martial arts.

Coach Leon Kallai

Jiu-Jitsu/Judo Coach

Leon Kallai began his martial arts journey in 1995, starting Judo as an eighth grader searching for discipline and direction. What began as a positive outlet quickly became a lifelong pursuit. He went on to wrestle for North Valley High School while continuing to compete in Judo tournaments throughout the off-season, eventually earning his Judo brown belt.

As a competitor, Leon medaled in every Judo tournament he entered — approximately 15 events — and was a multiple-time medalist at the Oregon State Games, including a silver medal in the brown/black belt division. While he later competed in Brazilian Jiu-Jitsu, injuries limited his ability to pursue competition extensively as an adult. His focus ultimately shifted toward coaching, technical development, and mentorship.

Leon enlisted in the U.S. Army and served in Iraq before returning home and resuming his martial arts journey in 2008. He began training in Brazilian Jiu-Jitsu at Team Quest under Fabiano Scherner, where he built his foundation and continued evolving his grappling system. Through years of consistent training and coaching, he earned his Brazilian Jiu-Jitsu black belt in 2025. In addition to his martial arts career, Leon has also worked as a wildland firefighter, a role that reflects the same resilience, teamwork, and composure under pressure that he brings to his coaching.

Leon has been teaching Judo and Jiu-Jitsu in various capacities for over a decade and has worked with youth students since 2014. He is passionate about helping young athletes build discipline, confidence, and resilience through martial arts, and he is committed to creating a structured, positive training environment for the next generation. In addition to youth instruction, Leon looks forward to expanding Judo programming for adult students seeking to develop takedowns, balance, and stand-up grappling skills.

For Leon, martial arts has always been more than competition. It has been a stabilizing force and a path for personal growth through life’s challenges. He credits grappling and the martial arts community with helping shape the man he is today and is dedicated to paying that forward through coaching, mentorship, and leadership on the mats.

Coach Steven - Krav Maga

Coach Steven has been a Krav Maga practitioner for 12 years and became an instructor in 2019. He began his journey in 2013 where he had integrated a lot of mindsets for tactical and effective self-defense techniques, and to implement a psychology structure for helping himself and his students grasp a better understanding for relentless mindset in countering assailants, awareness, and safety.

Steven is also near the end of the Forensic Psychology Bachelors program where a lot of these rules and statistics apply to the world of self-defense, learning procedures, and demographics of criminal behaviors and queues.

Steven teaches Krav Maga as a purpose to help those who need assurance, and a skillset to be confident in themselves, and for those close to them to have a feeling of certainty if a situation arises. It strongly resonates with the quote “It is better to be a warrior in a garden, than a gardener in a war” Iron sharpens iron, and with that he believes we train together, we learn together, and with that we become stronger.
