Brandon Sowerby began training in Karate as a child and has been involved in sports, weight training, gymnastics,
and martial arts ever since. Combining his high achievement in Kempo (an art known for versatility) and a strong
foundation in Jiu Jitsu, Mr. Sowerby brings a Mixed Martial Arts perspective to the program. Through his studies
and experience, Mr. Sowerby has a profound understanding of human movement and body mechanics. These
traits combine to make Mr. Sowerby the ideal Chief Instructor for USSD in Sandy, Utah. While he does maintain
his reputation for winning first place trophies in nearly every USSD tournament event he participates in, Mr.

philosophy that by maintaining a balanced regimen of basics, self defense techniques, martial arts forms and
sparring, the student will acquire a well rounded skill set and aptitude for self defense. Native to Utah, Jason takes
pride in serving the Sandy, Utah community. Jason graduated the USSD Academy for Martial Arts Instructors in
2005 and has been teaching from this location since it opened in 2011.
