The newly appointed division head boasts considerable experience in the creation and production of large entertainment formats for television, beginning her professional career at Gestmusic, where she was responsible for projects including Tú sí que vales and OT castings. After 16 years with the company, Castellano joined the Banijay group to undertake a new stage in her career as executive producer and director of Dlo/Magnolia’s entertainment division, consolidating her position as a quality reference point thanks to productions with a distinct character of their own committed to excellence and innovation. The strategy garnered widespread recognition with critical acclaim and audience success, evidenced by the 2018 Ondas Award for Radio Gaga, the 2019 Iris Award for Joc de Cartes, the 2020 Cima Award for Pioneras, and several seasons of programmes such as Cero en Historia and Ruralitas. At the beginning of 2021, Castellano was appointed general director of Zeppelin TV, also part of the Banijay Group, with the company producing additional successes during her tenure, including LOL for Amazon and Secret Story for Telecinco.
