Nathaniel Dunigan is a social entrepreneur who created "Aidchild" to help orphans and vulnerable children suffering from AIDS in Africa. He first visited Uganda as a government official and was inspired to make a difference. He resigned his job, sold his belongings, and moved to Uganda to establish Aidchild. Within two years, Aidchild was chosen by Ugandan and American governments as a model for pediatric HIV/AIDS care across Africa. He has since opened a second center and treatment laboratory serving over 3,000 children and adults.
