After graduating in economics, he started working at SMH/Swatch in 1991 under the leadership of Franco Bosisio, almost immediately assuming responsibility for the Collectors Club.

In January '96 his path crossed that of the Romeo Gigli group for which he became press office and external relations manager.

In October of the following year he opened his own agency in the heart of Milan, the Antonio Gallo Immagine & Comunicazione, with which he carried out his first operations with a strong media impact, establishing himself as a point of reference in the fashion industry for clients such as Pirelli, Telecom, the Lineapiù Group, Samsonite Blacklabel, Giuliana Cella, Casa Damiani, Pelliccerie Annabella and Simonetta Ravizza by Annabella.
