Randall Studdard is from Alabama and graduated with a degree in forestry from Auburn University in 1973. After working in the forest industry for 10 years, Randall felt called to the ministry. He attended Bob Jones University and graduated in 1989. Bonnie is from Arizona and graduated from Bob Jones University with a B.S. in nursing in 1973. She served four years as a missionary nurse in Suriname, South America.

Randall and Bonnie were married in 1980. They finished deputation and language school in 1995 and began work in the Extreme North of Cameroon. They lived and worked their first five years in the market town of Kousseri, moving later to their present location of Makary, a large village of about 3,000. This region is 99% Muslim. A few of the small communities are made up of Protestants who have moved here for work purposes.

Their time in the Extreme North has been a pioneering work among small Arabic villages which dot the landscape for many miles all around. On Sundays, they preach and teach in a small church located about an hour from their home. About 15 to 20 persons attend each Sunday. These people are from a Protestant background. Bonnie teaches the ladies and children Sunday school classes. On Sunday afternoons Randall helps his co-worker, Zane Bachman, teach a men's Bible course that was started in 2006. Bonnie has two ladies' sewing classes where she gives Bible instruction. Each class is well attended and averages about 8-10 Muslim ladies from their home village of Makary.

The Lord has blessed them with seven children, John, James, Sam, Mark, Joe, Grace, and Hannah.
