The Slovak Studies Program at the University of Pittsburgh derives its resources from the Slovak Endowment, which has been established with the generous and vital support of the following fraternal organizations in the United States:
- The First Catholic Slovak Union;
- The Ladies Pennsylvania Slovak Catholic Union;
- The First Catholic Slovak Ladies Association;
- The Slovak Catholic Sokol;
- The First Slovak Wreath of the American Eagle (which in 1997 joined the National Slovak Society).
