Head Instructor, Brentwood Martial Arts
Over Three Decades of Experience
Dedicated to Student Development
Professional Biography:
Master William Sampson is a sixth-degree black belt and the Head Instructor at Brentwood Martial Arts, where he has been a cornerstone of the teaching faculty since 1997.
With over three decades of experience, Master Sampson is recognized for his deep commitment to technical excellence, student development, and the continued evolution of martial arts instruction.
His journey began in 1990, when, as a quiet and reserved child, he was enrolled in martial arts to develop the confidence, discipline, and resilience needed to navigate the social challenges of school life. Upon relocating to California, he formally began training in Chinese Kempo, quickly discovering a lifelong passion.
Brentwood Martial Arts was affiliated with a broader Kempo Karate organization known for integrating diverse disciplines—including Wrestling, Jiu-Jitsu, Filipino Martial Arts, Kung Fu, and Boxing—into its training methodology. This unique and comprehensive approach allowed Master Sampson to immerse himself in a multifaceted curriculum, further deepening his technical knowledge and philosophical grounding.
After earning his black belt, Master Sampson relocated to Los Angeles and began teaching at the Brentwood location, where he has remained ever since. His competitive career took him across the western United States, participating in regional tournaments and sharing the lessons of the mat with his students.
In the early 2000s, he was invited to join the instructor training program within the organization, mentoring the next generation of martial arts educators. Alongside a long-time training partner, he committed to continually refining the pedagogy, updating methodologies, and integrating contemporary principles while remaining grounded in traditional martial values.
Their work eventually expanded into teaching seminars and workshops across other regions. In 2018, Master Sampson was formally awarded the rank of sixth-degree black belt. Today, he continues to lead instruction for students of all ages and skill levels, maintaining an unwavering dedication to the craft.
Nearly 30 years since first stepping into the Brentwood dojo, he remains as inspired as ever—devoted to fostering strength, confidence, and character in every student he teaches!
