Genovese crime family. While Gigante served as boss on the streets, Cirillo served in a 'messenger' between Gigante and the other caporegimes of the Genovese crime family, as Cirillo's low-key style earned him his nickname "Quiet Dom" and helped him avoid the gaze of the authorities for many years. Gigante's acting boss After Gigante was imprisoned in 1997 for racketeering and conspiracy charges, the leadership of the Genovese crime family passed to a committee/ruling panel, known as the "Administration," ostensibly led by Cirillo. In this capacity, Cirillo represented the Genoveses in their dealings with the other Mafia families of New York City, though Gigante remained in overall charge of the family.

Cirillo was sentenced to 48 months in prison and forced to pay $75,000 restitution. Consigliere On August 22, 2008, the 79-year-old Cirillo was released from federal prison after serving more than three years. After being "acting boss" following the death of longtime family godfather Vincent "Chin" Gigante in December 2005, Cirillo began to serve as consigliere of the Genovese family. It appears that he had stepped down in 2015 to allow former street boss Peter "Petey
