These dedicated people have spent a decade or more volunteering their time and talent to Oasis’s mission and vision. Their wisdom, leadership, and service has greatly helped us be effective in publishing to equip discipleship across Africa and the world. With great appreciation and thanks (listed alphabetically):

Brian and Elaine Anderson,

Oasis Distributions Nigeria Managing Director (Brian), planted and watered the fledgling ministry as master gardeners with love and devotion for Nigeria and its people.

Craig and Beth Ewoldt,

Oasis Distributions Nigeria Managing Director (Craig), faithfully served in Jos Nigeria building the ministry and mentoring our leaders with great perseverance and dedication.

C. Jeff Wright,

of Urban Ministries Inc (UMI), board member, brings excellent advice and wisdom into every meeting. Jeff is a powerful advocate for African leaders having a prominent voice in the global church. UMI's partnership with the Africa Study Bible has been a great encouragement, empowering it to minister to the African American community.

Virginia Elliott,

board member, co-founded Oasis with her husband Edward Elliott in 1978. We can safely say that without her faith, encouragement, generosity, and steadfastness over the years Oasis would have never begun and never continued through the hard times.

Tim Martins,

board member, as CEO of Barbour Publishing was instrumental in Oasis's development and growth as an organization - especially in the areas of business, publishing, management, and development of the Africa Study Bible.


Steve Potratz,

His dedication to serving the global church has impacted Oasis's core values and our staff more than we could ever express. His legacy will forever influence our ministry and lives.

Paul Mouw,

full-time advocate and volunteer, came alongside us just when we needed it the most- to help complete the Africa Study Bible. As a communications and publishing “Professor" and expert from Judson University, Paul led, organized, served, and contributed in more ways than we can count.

Prof. Tite Tienou,

of Trinity Evangelical Divinity School, board member and chair, led the board through the crucial transition to becoming a publisher for Africa, including chairing the “Founding Committee of the Africa Study Bible.” His wisdom, godliness and African knowledge will inform our books and our culture far into the future.

Help us Satisfy Africa's Thirst for God's Word.
