Our Instructors

Professor Tyrone Angolia
Tyrone Angolia began training in Praying Mantis Kung Fu in 1994 and was fortunate enough to train with his Sifu for the next ten years. In 2003 he became a successor of the Chen Zhen Yi lineage of 7 Star Praying Mantis Kung Fu. In 2007 he began training MMA and then started to compete the following year. Thoroughly enjoying competing in MMA matches naturally led him to training in Jiu Jitsu.
Tyrone began training with Professor Ben Baxter in 2009, and currently holds the rank of 3rd degree black belt in Brazilian Jiu Jitsu. He currently teaches at Precision Martial Arts in Corvallis. Tyrone is a multiple time IBJJF Medalist, and brown belt American National Champion.
Tyrone’s path to excellence is paved by helping his students increase their kinesthetic awareness, neuromuscular connection and overall muscular endurance through martial arts and conditioning.

Coach Demian Hommel
I am a Professor of Geography at Oregon State University, and I intend to bring an educator’s mindset to my classes at Precision Martial Arts. While living in Thailand for four years to complete my graduate and doctoral research, I trained at a wide range of camps across the country, analyzing the diverse methods and the strengths of different systems. I’ve spent decades distilling those international experiences into a clear, teachable method designed to help you build applicable skills and confidence.
My teaching philosophy is pragmatic and evidence-based: I believe that with structured support and consistent effort, anyone can become a proficient striker. My goal is to break down the technical nuances of Muay Thai to make them accessible, effective, and rewarding.
