The Kieffabers, with World Indigenous Missions since 1990, are based in Altotonga, Veracruz, Mexico.

For years, they have lead film outreaches in many villages throughout Mexico, touching a number of indigenous groups.  Since 2001, the church they established in Altotonga has its own national pastor.  They now spearhead a Ministerial Alliance with the vision to see Altotonga and the entire region transformed by the Gospel. 

In addition, Jim and Ruth work closely with the leadership of Agua Viva de México, assisting that national church group in fulfilling the legal requirements established by the Mexican government.
