Our Instructors

Master Rachael Evans is the founder and chief instructor at Quantum Martial Arts, with over 35 years of martial arts experience. A sixth-degree black belt, she teaches a unique style of her own creation that blends Tae Kwon Do, Wing Chun, Judo, and Arnis, among other styles, in a challenging and positive learning environment. Master Evans resides in San Francisco but regularly travels to our other schools to work with our instructors and students.

Inspired by Bruce Lee’s performance in the movie Enter the Dragon, Master Evans first studied Shito-ryu as a youth. Martial arts has been a constant in her life, through a journey that includes management, music, bookkeeping, and the U.S. Marine Corps. She took her first Tae Kwon Do class from Master Mark Karasek in Twentynine Palms, CA, and studied under him for five years before returning to Seattle to teach.

Master Evans opened Quantum Martial Arts on Capitol Hill in Seattle in March of 1995 with just 8 students and 8,000 square feet of space. Since then, the school has grown to well over 100 students and moved to its current larger location in First Hill, Seattle.

Master Evans moved to San Francisco and opened a second Quantum Martial Arts dojo in the Mission District in 2007. The school has since grown from a handful of Seattle transplants to a thriving program for all ages that continues to expand. The Quantum style continues to develop as well, as her experience with yoga, body work, and healing arts deepens.

Mr Drew Uthman is our youth program leader at Quantum Martial Arts in Portland. Mr Drew began his practice with Quantum Martial Arts in San Francisco, CA over 15 years ago and holds the rank of first degree, black belt.

Drew has been practicing martial arts for most of his life with experience in Wing Chun, Karate, Tae Kown Do and other disciplines.

His deep understanding of martial arts and commitment to structure, balanced with a playful spirit, make him a fun and highly effective instructor for both youth and adult students.

When Drew isn’t at the dojo, he’s exploring 3D graphic design.

Mr Brandon Wharton is one of our volunteer assistant instructors at Quantum Martial Arts. Mr Brandon began his practice with Quantum in 2023 and currently holds the rank of blue belt.

As a child, Brandon practiced Tae Kwon Do for several years. He returned to martial arts when he attended a general class at Quantum with his son. Brandon then continued taking adult classes and went on to assist with the Quarks, Kids and Preteen/Teen classes.

Brandon is a dynamic, creative instructor with a talent for adapting his teaching style to meet students at their age and developmental level.

When he’s not at the dojo, you can find Brandon spending time with his family, biking or snuggling with his poodle.
