During his years of service, initially as a missionary pilot/mechanic, David successfully carried out several leadership roles, including chief pilot, program manager, and regional director for Indonesia.

He became a Christian at an early age and was nurtured in his faith by his family, as well as by his church and youth group. David received a Bachelor of Science degree in Missionary Aviation Technology from Moody Aviation, and holds a commercial pilot’s license with multi-engine rating, as well an airframe and power plant mechanic’s license. Prior to joining MAF he worked as a flight instructor with Moody Aviation for two years. 

In leading MAF, David relies on God’s guidance and actively seeks the counsel of the executive leadership team and the board of directors, as well as that of MAF staff. He says, “It is my desire to not only be a part of addressing the significant physical needs of isolated people, but to also help them grow in their walk with the Lord. I want the message of the gospel to be clearly displayed in all we do.”

David and Natalie reside in Nampa, Idaho, and have four children.

Dan and his wife, Tracey, began their missionary service with MAF in 1993. Dan was served as a pilot/mechanic in Nicaragua, then in Venezuela. After 11 years of service, he was appointed program manager in Shell, Ecuador, until 2009 when, with his help, that program transitioned into a national entity and affiliate.

For the next four years, Dan led the MAF programs in Latin America as regional director. In 2014, he responded to the request for assistance from MAF affiliate Alas de Socorro de Ecuador (ADSE), a role he held until becoming vice president for MAF operations in 2018.

Dan learned about missionary aviation and MAF in his 20s, while travelling overseas with a Christian music group. Sensing it would be a perfect fit for him, he pursued the Advanced Studies Program at Moody Bible Institute. He also earned his commercial pilot’s license with instrument rating at Moody Aviation.

Dan and Tracey enjoy music, leading a worship team, and teaching Sunday School. Recently relocated to the U.S.A., they look forward to becoming similarly involved in their new local church.

Dan shares, “I keep returning to God’s promise in Isaiah 41:10 whenever I start to worry about things. He is the One who keeps me and gives me strength.”

The Whiteheads reside in Nampa, Idaho, and have three children.

Prior to joining MAF, Aaron served as an associate pastor in Mountain Home, Idaho. A pilot who enjoys flying, Aaron's strong call to ministry and missions led him to apply his leadership and administrative skills to benefit MAF.

Aaron holds the degrees of Bachelor of Bible and Pastoral Ministries from Global University, and Master of Organizational Leadership from George Fox University where he invests some of his personal time as adjunct instructor.

Ruth and her husband Doug joined MAF in 2004 in a management role in Central Asia. Dedicated to help build God's Kingdom in unreached areas, Ruth applied her skills in education and spiritual formation to encourage the faith of missionaries serving with MAF and client agencies.  

In 2014, Ruth was appointed director of Member Care to provide Biblical counseling and discipleship to MAF staff families. Under her leadership, existing programs were strengthened, and new initiatives successfully implemented.

Ruth's keen understanding of the MAF culture and values, and the ministry impact of personnel functions, led to her current assignment in 2019. Ruth was the candidate of choice to succeed the seventeen-year incumbent, Gene Jordan, an MAF veteran of 42 years.

A graduate of Biola University with a Bachelor of Arts in Education, Ruth is also certified in trauma care, coaching, debriefing, and facilitation. A fifth-generation missionary who taught children and adults in Central Asia, Ruth served on the local school board and led an interagency member care team for some 500 expatriates working with international organizations.

Ruth and Doug have four adult children. The couple resides in Boise, Idaho, and worships at Calvary Church where they invest in young church leaders and Christian professionals.

Pioneer evangelism, church-planting, pastoral guidance, member care, and leadership development were activities that Joe carried out while fulfilling his financial leadership responsibilities.
