The first member of the DeMeo crew was 16-year-old Chris Rosenberg, who met DeMeo in 1966 when he was dealing marijuana at a Canarsie gas station. DeMeo helped Rosenberg increase his business and profits by loaning him money so that he could deal in larger amounts. By 1972, Rosenberg had introduced his friends to DeMeo and they began working for him as well. The additional members of the crew would come to include Joseph and Patrick Testa, Anthony Senter, Richard and Frederick DiNome, Henry Borelli, Joseph "Dracula" Guglielmo (DeMeo's cousin), and later, Vito Arena and Carlo Profeta. DeMeo joined a Brooklyn credit union that same year, gaining a position on the board of directors shortly afterward. He utilized his position to launder money earned through his illegal ventures. He also introduced colleagues at the credit union to a lucrative side-business, laundering the money of drug dealers he had become acquainted with. DeMeo also built up his loansharking business with funds stolen from credit union reserves.
