The Olsons direct the missions program of Amistad Cristiana Church in Mexico City and teach missions at Christ for the Nations Bible Institute. They train Mexican missionaries and help mobilize the Mexican church to fulfill the Great Commission around the world, with a focus on the least reached. The Olsons have four children and have been serving in Mexico for many years training missionaries and doing outreach across Latin America, Asia, Africa, and other regions. Their goal is to continue equipping Mexican missionaries and developing international teams to reach more unreached people groups.
