Geje Eustaquio trains at the famed Team Lakay, and like so many of the martial artists to come out of that camp, he studied at the University of the Cordilleras, earning both a Masters Degree in Physical Education and Bachelor’s Degree in Education. He began kickboxing at the age of 14, and soon transitioned to wushu, eventually being invited to join the Philippines national team.
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 for the ONE Interim Flyweight World Championship.
