With 30 years of professional experience, Angélica has promoted community participation and engagement processes by facilitating dialogue between various local actors. She has done so from various institutional perspectives: government, NGOs, local governments, consulting firms, and independently. This has allowed her to understand and address the complexity of social, territorial, and institutional processes.

Highlights of her career include piloting the citizen participation methodology in environmental assessment (PARTICIPA-CONAMA), which was later formalized in the environmental institutional framework, and leading dialogue and facilitation processes at the Ministry of Mining (National Lithium Strategy) and the Chilean Agency for Sustainability and Climate Change (Voluntary Pre-Investment Agreements). In addition, she has worked for the last 20 years as a consultant and facilitator of early citizen participation processes and business-community relations strategies in complex territories.

In the 1990s and then in the 2000s, she stood out for her work in various NGOs (JUNDEP, Policlínico San Luis de Huechuraba, CEDEM, and, fundamentally, the Casa de la Paz Foundation). These NGOs were important environments for teamwork, learning, and strengthening her professional work in communities.

In the academic sphere, she is noted for her role as Director of the School of Sociology and Social Work at the Universidad Academia de Humanismo Cristiano (2020-2024). She has 25 years of experience in undergraduate teaching (U. Arcis, U. Central, and UAHC) and in postgraduate programs in conflict mediation and community relations. She has also participated as a teacher in various training and academic management programs. 

She is a social worker and holds a master's degree in human settlements from the Pontifical Catholic University of Chile, as well as a diploma in gender studies and higher education.
