Deon & Rene Theunissen

Career missionaries since 2014, now serving as Field Directors in Southeast Asia.

We are the Theunissens, born and bred in South African. We have three happy God-fearing children, all with their own careers who live in South Africa. We were both called to be medical missionaries at a camp meeting in South Africa in 2008. We decided to wait until our children finished high school when we applied to AFM.

Currently, we are serving as field directors in Southeast Asia.
