Since 1991, Mark and Diane have ministered among the Kwong people in Chad Africa as missionaries with the Evangelical Alliance Mission. Their goal is to give the young Kwong church the spiritual depth, godly traditions, and numerical weight to enable it to endure for generations to come. This website describes their life in Africa over 20 years and their ministry among the Kwong. 

Diane is now on Facebook. You may look her up there, though you should know that she is rarely able to check her page when we are in Chad.

Also, we have tried our hand at posting a couple short videos on Youtube. One is about Kwong music and the other is for kids about making fired bricks.
