Philadelphia's Greek Mob, or the Greek Mafia, are a low-profile criminal organization of ethnic Greek Americans with alleged connections to the Italian Philadelphia crime family. They were formed in Greece by the original boss Steve Kondonyanis. Kondonyanis also had strong ties with the Efthimiades family of Macedonia. When the Efthimiades family was run out of power in the 1960s, Kondonyanis decided to move his operations to the culturally diverse America. When Kondonyanis was sentenced to jail to serve life for murder, mobster Chelsais Bouras took over.
