Asier Etxeandia left his native Basque Country and moved to Madrid when he was 20 years old. In Madrid he first worked as a sex shop assistant while also taking acting classes. In 1995, he debuted on TV as a contestant in the game show Uno para todas (Telecinco), presented by Goyo González. The production company Globomedia hired him for the first season of Un Paso Adelante, where he played Beni, a gay student who enrolls in a Performing Arts school to become an actor. Etxeandia left the series because he feared becoming typecast. In spite of this, he recognises that this role opened doors and got him his first friends in the Business, among them Actress Natalia Millán.
