Teresa Valero was born in Madrid in 1969. Passionate about animation and drawing from an early age, she struggled to pursue her studies in these areas in Spain. She finally received administrative training, before joining the Lapiz Azul studio in 1990, doing pre-production work for TV series including "Tintin" and "Rupert." It was there that she met Juanjo Guarnido and Juan Díaz Canales, with whom she soon became friends. Thanks to them, she also discovered the world of comics. Following her time at Lapiz Azul, she went to work for the Milimetros studio as a pre-production coordinator for series such as "The Pink Panther," "Babar," and "Madeline," as well as feature-length films ("Asterix in America"). In 1996, alongside Juan Díaz Canales, she co-founded Tridente Animation, where she continued her work in television and film. In parallel, she began to offer classes on storyboarding, animation, and narration at the University of Madrid. Her own work in comics would soon follow, with "Sorcelleries" (Dargaud) and "Curiosity Shop" (Glénat). Her most recent graphic novel is the ambitious "Gentlemind," alongside Juan Díaz Canales and artist Antonio Lapone (Dargaud, Europe Comics in English).
