Jeff Turnbough joined ITA in November of 2015 as the Chief Executive Officer (CEO).

The son of Reverend Elmer and Gladys Turnbough, Jeff was born in St. Louis, Missouri, USA on September 8, 1955. Jeff followed Christ at the age of nine in the local church his father pastored. He graduated from Welch College with a B.S. in music and Christian education (1977) and a B.A. in biblical studies and missions (1979). He sensed God leading him into missions while studying there. Jeff holds a Diploma of Estudios Hispánicos (Hispanic Studies) from the University of Madrid and an M.A. in theology and missions from Grace Theological Seminary. He graduated from Biola University in 2004 with his doctorate in missiology. His dissertation focused on a qualitative study of the conversion process for evangelical Spaniards in Madrid.

Jeff married Susana Crowson in May 1975.

The Turnboughs were appointed to missionary service in April 1981. They went to Spain in June 1982, as church-planters. After completing two years of formal language study, they were used by the Lord to plant the first Protestant church in the growing city of Collado Villalba on the Northwestern side of Madrid. The couple helped develop a church-planting team, they served as field leaders for the Spain team, then regional directors for Europe. Jeff also served seven years as director of field operations, a role that moved the couple from Spain back to the United States for a period of time.

The Turnboughs have two adult children: Matthew and Melissa.

Matthew married Brooke (Atwood) in May 2002. The couple works via a social outreach ministry in Spain. They have three children: Andrew, Caroline, and Daniel.

Melissa married Mason Mandy in 2006. Melissa is an RN and Mason is a surgeon. They live in Phoenix, Arizona with their three children, Liam, Sofia, and Josué.

Jeff and Susana lived in Spain from 1982-2012, were back in the USA serving in their mission’s home office for several years, and then moved back to Spain in 2020, and are currently living and working from Spain.  Jeff and Susana have dual citizenship.
