Piet Wilhelm is a retired United States Marine honorably discharged from being an infantry platoon leader. He taught recruits and members of the armed forces in close combat and martial arts where he found his calling as a civilian. As a Brazilian Jiu-Jitsu professor, Piet is the founder of the Triton Fight Center's and operates his own facility with his wife Sara in Broken Arrow, Oklahoma.

Piet Wilhelm is the only child of Mr. and Mrs. Wilhelm. Piet is the first family member of the Wilhelm’s to enter the world of Brazilian Jiu-Jitsu.

Before Jiu-Jitsu, Piet began his military adventure in 1990 by joining a military academy to later receive an appointment to a service academy in 1994. His desire to serve his country lead him to enlist from 1996 to 2005. While serving he deployed to Diego Garcia, Bahrain, Turkey, Greece, Italy, Kosovo, Albania, and the closing of military bases in Panama. During his tour as a Drill Instructor his father was brutally murdered, rendering a decision to leave active duty and go into the reserves. Although no longer a man in camouflage his desire to help those who serve continues. He started a Local Heroes Program at his facility in Broken Arrow to help prior military adapt to civilian lifestyle and to combat PTS and TBI. Currently the ONLY martial arts facility recommended by the Veterans Affairs in the Tulsa metropolitan area.

Now with over 20 years of training martial arts, Piet Wilhelm is considered by many to be one of the top Brazilian Jiu-Jitsu Instructors in the Midwest.  Piet received both his blue belt and his purple belt from Henrique Stefani who happens to be a black belt under Master Renato Tavares. After Henrique relocated his family to Brazil, Piet then became a student under Renato Tavares, where he earned brown belt and black belt (October 23, 2010).

Since Piet has been in Tulsa, he has lead many people to success. He is the founder of The Triton Fight Center's, where many mixed martial arts fighters and Brazilian Jiu-Jitsu players come to train. Piet continues to work with his team of students as a professor, coach, and friend. Piet has remained loyal to his instructors and the Renato Tavares Association, where LOYALTY and RESPECT are some of the most admirable qualities.
