Hernandez Martial Arts is a third-generation, family-run, family-owned martial arts school that has served Union City families since 1982. It blends the tradition of karate with modern advanced training methods, combines physical training with proven teaching methods, and offers age-specific martial arts programs for kids and teens. The program includes an exclusive character development program and focuses on developing the whole child, not just teaching martial arts techniques. Hernandez Martial Arts provides martial arts classes to families from Union City, Fremont, Hayward, and surrounding areas and is described as a trusted martial arts school in Union City for over 44 years.

Parents describe the instructors as teaching and leading with kindness and say they instill discipline, respect, and leadership in their students. One parent reports a huge improvement in a daughter’s self confidence after a year in the program, and another notes that a son’s training has supported confidence, responsibility, and strong academic performance. A parent whose child has attended for a month reports already seeing a noticeable increase in the child’s confidence.
