Martial Arts

Martial arts saved Piet Wilhelm's life. Not in the dramatic sense—but in the most important way: it gave him confidence, resilience, and a pathway to transform childhood adversity into lifelong purpose.

The Beginning: Overcoming Adversity

As a young boy, Piet faced bullying and knew he had to change. His father's words became his compass:

  • "No one is coming to save you."

Rather than defeat, those words became a call to action. Piet began training in karate and boxing, determined to build the physical strength and mental toughness he needed. Over time, he expanded his training to include wrestling, judo, and No-Gi Jiu-Jitsu—disciplines that would prove invaluable when he joined the Marine Corps.

From Student to Instructor

During his military service, Piet became an instructor in both Close Combat and the Marine Corps Martial Arts Program (MCMAP). He wasn't just learning anymore—he was responsible for developing other warriors, instilling in them the discipline and mentality required to serve.

The Journey to Black Belt

After leaving the Marine Corps, Piet deepened his commitment to martial arts. He trained in Muay Thai and Brazilian Jiu-Jitsu under respected instructors, ultimately finding his home in BJJ. Under Master Renato Tavares, one of the sport's most respected figures, Piet earned his journey through the ranks:

  • Blue Belt (under Henrique Stefani)

  • Purple Belt (advanced training under Henrique)

  • Brown Belt (continued development under Master Renato Tavares)

  • Black Belt (earned after years of dedication, perseverance, and service to the art)

Tested Through Competition

Piet believes training must be tested in the real world. He competed extensively in both Brazilian Jiu-Jitsu and Mixed Martial Arts at local, national, and international levels.

His competition accomplishments include:

  • Multiple IBJJF Open Championship Gold Medals

  • IBJJF Pan Championship Bronze Medal

  • U.S. National Championship Medalist

But for Piet, competition was never about medals—it was about growth. Victories taught him gratitude and humility. Defeats taught him perseverance and self-awareness. Every mat experience shaped who he became as a leader and mentor.

Building Triton Fight Center

Today, as the founder and owner of Triton Fight Center, Piet dedicates himself to helping others discover the same confidence, discipline, and resilience that martial arts gave him. What started as a training academy has become a community and launchpad. Several of Piet's students have gone on to open their own academies throughout the region, and he continues to mentor academy owners on the business side of martial arts.

Service Beyond the Mats

Piet generously donates his expertise to law enforcement, first responders, and military personnel across Oklahoma. Through the Local Heroes Program at Triton Fight Center, he supports veterans and first responders navigating service-related challenges. For Piet, martial arts has always been about more than technique—it's about building character, developing leaders, and serving others.
