Diego Paez hails from Southern California, where he perfects his striking craft at Classic Fight Team in Fountain Valley.
The Colombian-American began training Muay Thai at 15 years old and, developing a passion for competition, had his first fight four years later.
As an amateur, Paez went a blemish-free 10-0 on the national circuit before turning professional in 2017. Once in the upper echelon of the local Muay Thai scene, he won the WCK 130-pound Championship and four other titles.
In 2025, Paez took his accolades, technical aggression, and explosive skills to the world’s largest martial arts organization, where he aims to become a mainstay among the most elite flyweight Muay Thai fighters on the globe.
