Sombrilla’s longest partnership is with ADIM, a registered NGO in Guatemala. Indigenous communities in northern Guatemala suffered through a thirty-year civil war that ended in the 1990s. Sombrilla was founded in 1987 in response to human rights abuses and population displacement that occurred as a result of the war. The primary goal of Sombrilla was to promote peace initiatives, and later to provide development aid and support for communities in the Quiche region. Early projects included:
- Promotion of Participatory Democracy and Gender Equity Project
- Human Rights and Peace Accord Promotion Project
- Primary Health Care Project – Phase 1 and 2
- Improved Stove and Corn Grinder Project
- Comitancillo Human Resource Development Project I and II
- Ixcan-Sierra Prevention and Reintegration Project
- Ixcan Water and Latrine Project
- Teacher training and Library Building
- Ixcan-Sierra Wellness
- Chajul Family Garden Project
