The William B. Wiener Jr. Foundation concentrates its entire documented giving on a single intermediary, the Rockefeller Family Fund, providing unrestricted operating support that advances human rights, education, and other public-benefit causes. Although based in Shreveport, LA, the foundation's funding is clearly national and focused on strengthening a grantmaker that in turn supports public policy and social-justice work. Its approach is streamlined and strategic: big, unrestricted gifts to a trusted partner rather than many direct grantees.
Highly concentrated: very large, repeat grants exclusively to a single national intermediary (Rockefeller Family Fund), providing general operating support rather than many small or direct program-specific awards.
