Our Founder’s Story

Mario was born in El Salvador and emigrated from El Salvador to the US at 8 years of age in October of 1981. He crossed the US-Mexican border on foot with a “coyote” as an undocumented immigrant 24 hours after his mother and brother crossed on foot themselves, also with a “coyote”.
