While planting a church in Paraguay, Alfredo and his wife Yolanda were inspired by a noble gesture of an anonymous entrepreneur who sent them small but useful monthly offerings that were used to buy Bibles and chairs for the church. They prayed to God that one day they could also help those working in the field through small monthly contributions and biblical literature.
God used Robert and Carolyn LeMaster to advice Alfredo and Yolanda in the shaping of Mies Foundation. LeMaster Foundation became the mentors of Mies Foundation. To this day, Mies Foundation has supported over 60 Christian workers around the world and has placed over 4,000,000 Biblical Literature (Bibles, New Testament, Gospels, Tracts) in the hands of those who need them.
