A member of Republican Proposal (PRO), Torello has served as National Senator representing Buenos Aires Province since 2022, in replacement of Esteban Bullrich.

Torello was born in Buenos Aires on 19 February 1960 into a wealthy family linked to the agricultural business.

He is a grand-nephew of Pablo Miguel Torello (1864–1943), who was Minister of Public Works during the presidency of Hipólito Yrigoyen.

Torello attended Colegio Cardenal Newman, an elite private boys' school, where he met future president and collaborator Mauricio Macri.

He eventually left the firm to work for Mauricio Macri upon his entry into politics in 2003, becoming a founding member of Republican Proposal.
