Dedicated to working against the 'Ndrangheta organized crime syndicate, Gratteri is leading the prosecution of more than 350 of its members and allies.

In January 2021 Gratteri began a trial that is the culmination of four years of investigation of Italy’s most powerful mafia group.

He grew up in mafia-dominated Calabria. Many of his childhood companions were born into ‘Ndrangheta families joined the business. Gratteri instead became a prosecutor determined to bring down the mafia.

His battle against narcotics trafficking has been focused and relentless. The success of an operation run with the assistance of the FBI, reinforced the importance of international collaboration and cooperation in this battle.

Gratteri has been a Special Prosecutor for Reggio Calabria since 2009 and currently serves as an Advisor to the Italian Parliamentary Anti-Mafia Commission.

On the front lines against the 'Ndrangheta for decades, Graterri has lived under the projection of the police and private bodyguards since 1989.

He is the author of several books including Acqua Santissima, written with the historian Antonio Nicaso, which exposes the dense relationship of the church and the ‘Ndrangheta, spurring the present Pope into making his most recent appeals to Mafiosi to repent.
