A lifelong fan of martial arts, Geje Eustaquio was inspired by Bruce Lee to begin kickboxing at the age of 14, and soon transitioned to wushu where he eventually won a Filipino championship before joining the Philippine national team. After training under famed coach Mark Sangiao for several years, “Gravity” inevitably joined Sangiao’s Team Lakay. Like so many of the world-renowned martial artists to come out of that camp, he studied at the University of the Cordilleras, where he earned both a Masters Degree in Physical Education and Bachelor’s Degree in Education.
After graduating, Eustaquio became a teacher, but his heart yearned for action, prompting him to quit and pursue his martial arts dreams. He made his professional cage debut in 2011 a successful one, winning by first-round TKO. The following year, he signed with ONE Championship, and claimed several impressive wins over top contenders to earn a shot at the inaugural ONE Flyweight World Title.
Though unsuccessful in his first title bid, Eustaquio remained steadfast in his pursuit of a world championship, establishing himself as one of the top competitors at both flyweight and bantamweight over the course of his career in ONE Championship. Finally, at ONE: GLOBAL SUPERHEROES in front of his fellow countrymen in Manila, his dreams came true when he defeated former titleholder Kairat Akhmetov to claim the ONE Interim Flyweight World Championship.
