ASEI’s mission is to provide credit to micro-enterprises in an effort to provide the highest quality services. Established as an NGO in 1992, ASEI is dedicated to following the Grameen Bank model invented by Muhammad Yunus. ASEI was first supported by Catholic Relief Services in 1993 but has since received support from USAID, ACOVI, KATALYSI, and ALPIMED.
ASEI currently has four regional offices located in San Salvador, Cojutepeque, San Miguel, and Santa Ana and has more than a thousand community banks in the country. The NGO is governed by a general assembly of 12 members who meet annually and democratically name the Board of Directors.
