Being unsuccessful at starting a family, Ron and Peg pursued an international adoption, culminating in a six-week trip to South America in 1990, where they adopted their son, Benjamin Ramón. Ten months later, Peg gave birth to Allison Maria!
The Lord opened their eyes and hearts to overseas missions on that adoption trip, so they left their careers in 1992 and moved to Jackson, MS to attend Reformed Theological Seminary.
Following seminary and Ron's ordination, the Smiths joined MTW's Guayaquil, Ecuador Church Planting Team, where they served from 1996 to 2005. Ron and Peg began English conversation clubs and classes, children's ministries, women's Bible studies and couples' ministries -- all with an evangelistic thrust. Peg taught Sunday school and trained others to teach, while Ron was involved in discipling and counseling, as well as planting and pastoring San Agustín Presbyterian Church.
