Biography Mónica Arce was born on 2 March 1986 in Santiago to Sergio Enrique Arce Álvarez and María Teresa Castro Carranza. She completed her secondary studies at the Colegio de Adultos Manuel Bulnes in 2004 and obtained a degree in Logistics Engineering from the Instituto Profesional Cámara de Comercio de Santiago.

Before entering politics, she worked in logistics and co‑founded the Fundación Alma Libre, an organization that supports trans children and their families.

In March 2025, she was referred to the Chamber’s Ethics Commission after missing a mandatory drug test. Arce argued her absence was due to her participation at the 69th session of the UN Commission on the Status of Women in New York.
