Atty and Henk Hammer laid the foundation for Sibusiso 25 years ago by purchasing a plot of land in Arusha. They envisioned a center where therapists and caregivers would have a place to support children with disabilities, so they would not remain isolated at home or in a hut. Next year in Tanzania, we will celebrate the center’s 25th anniversary. For the anniversary celebration in the Netherlands, the children and parents from the center have prepared a wonderful surprise for their “Mama Atty”. As is customary in Tanzania, there will be singing and dancing—watch the heartwarming video.
