Gustavo, accepted Jesus as his Lord and Savior when he was 15 years old. He was taken in as a foster
son by Doug and Shelly Kallestad in Chile.
In 1999, he traveled to Spain and Northern Africa to see firsthand the possibilities for a Chilean to
minister in the Muslim world. He then received an invitation to work with a team of church planters in
Melilla.
While serving in Melilla, Gustavo met and fell in love with Karissa, the daughter of a family serving on
the same team. They were married in June 2006, and now have four children.
After a decade in Melilla the Guevaras have returned to Chile, where they are serving in the South of
Chile though worship ministry, church planting and leadership development.
