Through its Thrive Social Justice Fund, ABS&P contributes grants to Anak Terlantar and helps raise awareness of its vital work—particularly in Indonesia, where the Foundation currently supports medical initiatives and provides annual funding to the Eagle’s Nest Orphanage in Semarang. We are inspired by the Foundation’s hands-on approach and its unwavering commitment to dignity, care, and opportunity for every child it serves.
