Since 2024 Andy has been an instructor at Canada Institute of Linguistics (CanIL, in Langley, BC), where he helps train others to serve language communities worldwide. Mary Ellen is part of CanIL's Community Life team—supporting the emotional, relational, and spiritual growth of the students. She's also involved with recruiting people to study at CanIL. The Fausts live in the Vancouver area.

After a decade in the field of English language teaching, Andy joined Wycliffe in 1999 and went to Central Asia to help develop an English learner’s dictionary. There he met Mary Ellen, who was a staff member of InterVarsity Christian Fellowship focused on evangelism and discipleship among university students. They married in 2001 and their two children were born while Andy was studying at CanIL. In 2007 Andy joined an existing translation project in Central Asia and his team published a full Bible in 2016. He went on to work in communications and another Scripture project in that region.

Andy and Mary Ellen consider it a privilege to be preparing the next generation for involvement in Bible translation work and missions around the globe!
