Sabine has been an ambassador of the Belgian ngo Cunina (Latin for 'Goddess of the Cradle') for 30+ years. Since 1989, Cunina builds and renovates schools, dining rooms, dormitories and sanitary facilities, educates the teachers and puts 1000s of children on school desks in Nepal, Brazil, South Africa, Philippines, Haiti, Peru and Uganda, thanks to long-term partnerships with companies, donations, inheritances and individual sponsorships. Cunina deliberately operates without government subsidies and spends 0 euros on paid advertising. Our overhead costs are under 10%, which is very exceptional. So more than 90% goes to where it belongs: our 1000s of children.
