We are a national organization of men and women who represent the estimated 26 million Americans of Italian Heritage, dedicated to promoting our culture, our traditions, our language, the legacy of our ancestors, and our contributions to the United States of America and the world.

We are sons and daughters, grandmothers and grandfathers.

We are corporate executives, and we are union members…

Young students and retirees…

Teachers and attorneys…

Doctors and firefighters…

Bakers and Wall Street brokers…

…and everything in between.

We are philanthropists, and we are model global citizens with purpose beyond ourselves. And we are proud and patriotic Americans of Italian heritage. We exemplify the very best of what it is to be Italian American.
