21. Frank Castagna

Frank Castagna has been a driving force in the real estate development and management business for more than 50 years with Castagna Realty. He’s been associated with Long Island Universtiy for decades, serving for nine years as chairman of the Council of Overseers for the Rose and Gilbert Tilles Center for the Performing Arts, collaborating with the Tilles family to fulfill the vision of a great cultural arts center on Long Island. The philanthropist also serves as president of the board of trustees of the Nassau County Museum of Art and is on the board of directors of both Old Westbury Gardens and the Anti-Defamation League. Castagna has also given us the Americana Mall—L.I.’s own Rodeo Drive. It is the place to shop and to be seen. And if you are shopping in the stores at the Americana, well, you might be a Power Lister yourself one day.
