Dax W. Crocker is a U.S. Latino who as a child migrated to the U.S. during the Central American civil war. Migration runs through his veins. His ancestors migrated from Ireland to the U.S. in the late 1800s and settled in Guatemala. His hometown is Los Angeles, CA where he was ordained to the ministry in a Latino Pentecostal organization. After missionary work in Sweden, Italy, and Spain he came back to the U.S. and pastored churches in Providence, RI and Tucson, AZ. It was in Arizona where he witnessed U.S. citizen children being left in foster care when their parents were deported in the aftermath of SB-1070.
