Susan and her husband Dave were born and raised in Cornwall, Ont. and Toronto, respectively. They joined Wycliffe in 1985 and went to West Asia two years later. They spent their first three years in a translation project, then six years in administration (Dave was field director while Susan was finance officer, then group librarian). From 1999 to 2002, they helped establish a training institute that continues to equip nationals for Bible translation work. In September 2002 they moved to Chiang Mai, Thailand, where Dave taught in a Christian university and served in administration and Susan served in various capacities in the SIL office (including cashier).
In July 2006 the Jefferys moved to Abbotsford, British Columbia and joined the staff of the Canada Institute of Linguistics (CanIL), Wycliffe Canada’s linguistic training facility on the Trinity Western University campus. Dave served there as VP for Academic Affairs and course head for two courses, before retiring in the spring of 2020. Susan manages CanIL’s linguistics library.
The Jefferys have two children, Robby and Leanne, both of whom married in 2016 and live with their spouses in Abbotsford.
Susan and Dave are grateful to God for the privilege of helping train the next generation of Bible translators and literacy workers. Many of their students have gone on to serve globally with Wycliffe and other translation organizations.
