"My son started Karate with Master T about 18 months ago... He listens, looks, learns, and has developed a great sense of leadership. His leadership abilities have transferred into his Kindergarten class at school and his Sabbath School class."

Kempo Karate is a self defense art that blends modern effectiveness with traditional values. Having served in the United States Marine Corps, Master Terrell leads a dojo where all classes are taught with discipline and purpose.
Our personalized attention, and sensitivity to your needs, make sure every class is an opportunity to grow— mentally and physically.
Our biggest impact shows up at home. Students become more coachable, more respectful, and more resilient— our families feel supported by a dojo community that genuinely cares about their loved one's growth.
Master Terrell began his martial arts training at age 12. While stationed at Camp Pendleton during his final year in the Marine Corps, he discovered USSD and joined the Oceanside dojo— eventually becoming Chief Instructor.
Inspired by his faith in Christ, Master Terrell knows he has been given a special gift and he wants to share that gift which is to teach life lessons through martial arts; that anyone can benefit from the character building Karate has to offer.
A leader among USSD instructors, he also serves in his church’s American Sign Language (ASL) ministry as an Interpreter. He also enjoys time in the ocean with his Sea-Doo.
Sensei Elias started training at USSD Oceanside in the summer of 2016, and by 2019 he was already giving back as a Red Belt on the S.T.O.R.M. Team (Special Team Of Role Models)—helping lead by example and set the standard for younger students.
Elias earned his 1st Degree Black Belt on January 6, 2024, and on November 18, 2025, he was officially promoted to the title of Sensei. What drives him most is simple: teaching the skills and principles that helped shape who he is today—and passing that confidence, discipline, and character to the next generation of Oceanside students.
Sensei Garrett Glassel began his martial arts journey at 8 years old and earned his black belt at 15½.
After helping with classes as a brown belt, he officially joined the instructor team around age 16.
For Sensei Garrett, teaching martial arts is fun, fulfilling, and uniquely rewarding. He loves watching students of all ages grow in skill and confidence. Just as important to him are the relationships built on the mat, which, over time, turn the dojo into a true training family.
