Nick Archer

Nick Archer

Vice President

Nick has worked in international development and mission work for over 30 years, half of which have been in Africa. He has served with World Concern for the last 15 years, and holds a Masters Degree in Rural Social Development.

“We have the privilege of serving some of the most vulnerable people around the world at a time when conflict and climate change are undermining people’s ability to not only provide a meaningful future for their families, but even survive,” explains Nick. "Poverty, in its myriad forms, continues to extinguish the dignity of many, rob children of their childhood, and consign people to a life without hope. Our work is to stand alongside those we serve, and reflect in what we do, how we do it, and what we say, the love and grace of God at the point of peoples' need.”

I am blessed to support such a dedicated team working so hard to create sustainable water systems, develop community managed financial institutions that bring affordable and convenient financial services to the very poor, and improve food security and nutrition to impoverished families.”
