 Originally a medical doctor in the US Air Force, D'Agostino joined the Jesuits early in his career, focused on psychiatry, and held various teaching positions.But it was through his experience working with multiple Jesuit charities that D'Agostino learned of the dire need for specialized facilities for abandoned children in Nairobi, Kenya.Today over 100 orphans or abandoned children live at Nyumbani Children's Home located in Karen, Nairobi.
