About NIXA

NIXA Martial Arts Institute was founded in 2017 by Master Ian Yu and Master Yong Jin Park. With its headquarters based in Ladera Ranch, California, NIXA quickly established itself and became one of the well-known martial arts school in the area. With their burgeoning success, NIXA expanded to open a second location in Yorba Linda, CA in 2020 with Master Alfred Rhee and Yoon G. Chang. With great synergistic work between NIXA Masters, NIXA Martial Arts has become one of the most prominent martial arts schools in the Southern California region to date and has produced a great number of National Champions since then. All of our instructors and staff members strive to create a positive yet disciplined environment where students can cultivate their physical, mental, and spiritual strength while building confidence, social skills, and anti-bullying techniques. We believe these life skills will allow them to be productive and respected members of society.
