Upon their arrival in Argentina in 1976 their passion to plant churches began to bear fruit.
During their first thirteen year the Exleys were involved in church planting efforts in several cities of Argentina and in Mexico City. Some of these churches have grown to many hundreds of members and together these churches have planted more than two dozen other churches. At the same time teaching in Bible schools was a rewarding and an enjoyable part of their ministry.
