Frank was born in Eindhoven, the Netherlands and studied tropical forestry and wildlife ecology on the Agricultural University of Wageningen, the Netherlands.

In Zambia he worked as a Conservation officer for several years and since 2004 he is working for ARK Nature, a Dutch NGO focussing on nature restoration.

For ARK he worked as a project leader for nature restoration projects in the Netherlands, Latvia, Croatia, Bulgaria and recently also in Ukraine and Germany. In most of these projects  he was working with large herbivores, and especially with wild living horses.

To his understanding and conviction wild horses and wild cattle are crucial for a natural mosaic like landscape that ensures a high biodiversity. And having these animals as key figures for wild nature, these animals  should be wild as well,  without human intervention like it once was before!
