Walter teaches at Lumino School for Disabled Children. He also provides support for many homebound disabled children in the surrounding villages by visiting their homes, teaching them, and helping their caretakers.

In his role on the SIJN Project Team, Walter helps facilitate the Child Evangelism Training, which is held at his school. He co-leads the group of teachers who meet each month to share their experience in starting and running Good News Club in their homes, schools, and churches. He works with Victor to plug young people who have committed their lives to Christ into local churches where they can become grounded in their faith. Walter is part of the team who sorts items from the container we ship from the US to ensure those things designated for Bible studies and Good News Clubs are used most effectively.
