Addo and his Dutch wife Petra van Liere-Addo. They work on small-scale projects together with other local partners and work with a team of volunteers in Ghana and the Netherlands.

Through its projects, the Foundation contributes to poverty reduction, (improved) education, access to healthcare facilities and basic amenities in Ghana and the rest of the African continent.
