Born and raised in California, Liam Harel has been doing martial arts since he was 5 with his twin brother Edan Harel; motivated by their father Opher Harel, who is also a self-defense instructor. Liam began doing kids Krav at age 7, Â he was in the kid’s program until the age of 13, from then on he participated in the adult classes. At the age of 15, he began the I.D.P program (Instructor development program) and continued to persevere and became a fully certified instructor by age 17 along with his brother. Along with his colleagues, his mentality is to teach others as many times as it takes so that they can feel comfortable walking on the streets alone, or with others. Outside the gym, he is a full-time student, studying criminology to become a police officer.
