Organized crime syndicates in the country of Greece and The United States. Most of the organizations in America operated alongside Italian-American families such as the Lucchese, Genovese, and Gambino Crime Family up until 2001, when associates of the Gambinos, Anthony Moscatiello, Tony Ferrari, and James Fiorillo had murdered several members such as Gus Boulis, owner of SunCruz Casinos, in south Florida.
The Greek-Americans operate mostly in areas on the east coast such as Boston, Philadelphia, and Queens, New York where the Valentzas Family and other groups allegedly control underground casinos and gambling rackets. Tarpon Springs, Florida is also home to many Greek-American groups such as the Pappas Family. There are unrelated organizations in Greece, predominantly on the islands of Cyprus, Crete and Chios.
