Owner & Chief Instructor: Master Robert “Bobby” Nelson

Trifecta Martial Arts was started in 2022 by Master Nelson after he moved from the Pacific Northwest to Los Angeles, CA. Trifecta Martial Arts was founded on the idea that traditional martial arts training should be fun, accessible, and practical. The purpose of our program is to make a meaningful impact on our students and our community through the training and camaraderie of Tang Soo Do.

Trifecta Martial Arts is affiliated with the World Tang Soo Do Association. Schools affiliated with the WTSDA gain access to seminars, tournaments, and instructors all around the world. Southern California has many WTSDA affiliated schools. Students who train with us may get to train with the occasional guest instructor. Some of the guest instructors from the Los Angeles area include:

Guest Instructors:

  • Master Ricardo Hassan – 5th degree black belt – Caltech Tang Soo Do
  • Master William Glenn – 5th degree black belt – Caltech Tang Soo Do
  • Mrs. Julie Galles – 2nd degree black belt – Mobius Tang Soo Do
  • Mrs. Megan Galles – 1st degree black belt – Mobius Tang Soo Do
