Roberto Arroyo

Political career In his public trajectory, his participation in the Vicariate of Solidarity during the 1980s stands out. He took part in the implementation of a dental rehabilitation program for women at El Manzano Prison in Concepción. In the professional sphere, he served as president of the Oncology and Reconstructive Foundation and of the Ibero-Latin American International Dental Federation, headquartered in Mexico.

As a member of the Party of the People (PDG), in August 2021 he presented his candidacy for the Chamber of Deputies of Chile for the 20th District—comprising the communes of Chiguayante, Concepción, Coronel, Florida, Hualpén, Hualqui, Penco, San Pedro de la Paz, Santa Juana, Talcahuano, and Tomé—in the Biobío Region, for the 2022–2026 term. On 21 November of that year, he was elected as a deputy with 9,458 votes, corresponding to 2.73% of the valid votes cast.

On 13 December 2022, he ceased to be a member of the Party of the People, and in 2023 he joined the Christian Social Party.
