Sumak is a member of the Cacha community, part of the Puruwa nation in Chimborazo province, Ecuador. She began serving as a UN Volunteer as part of the partnership between the United Nations Development Programme (UNDP) and the Global Environmental Facility (GEF) in 2017, after working for women's rights in the Ecuadorian National Assembly.

In the process of finding a right programming partner, I was able to get in touch with UNLIREC- the Regional Center for Peace, Disarmament and Development for Latin America and the Caribbean, part of the UN Office for Disarmament Affairs.
