B'nai Brith Youth Organization (BBYO) and all of its affaliates are non-profit organization (NPOs). David Berger was a Jewish wrestler from Cleveland, Ohio who died in the 1972 Munich Olympics from a terrorist attack. As a result, a chapter was created in Cleveland for the Aleph Zadik Aleph (AZA, the boys chapters in BBYO). Since this is a NPO, donations are welcome.
