While graduating from Paris CNSM (where he successfully obtained a First Prize in Gregorian choir conducting), he also studied conducting with Philipe Cambreling at Chalon sur Saône CNR, Tomáš Koutník at the Higher Music Conservatory of Prague, and then with Laurent Gay at the Geneva University of Music, where he got a Master of Arts in conducting. Nicolas Pasquet, Ronald Zolmann, Jiří Bělohlávek, and Arie van Beek, Jesus Lopez Cobos are among his advisors.

Florent Mayet conducted the Geneva Chambre Orchestra, the Geneva HEM orchestra, the Sinfonietta Orchestra, the St Etienne Sylf Orchestra, the Lyon Les Archétypes Orchestra and Unisoni Orchestra. Those activities lead him to conduct numerous concerts, with soloists such as Pascale Feuvrier, Gilles Henry, Jamal Moqadem…

Passionate about lyrical art, he participated in several productions as an assistant conductor at the Lyon opera house (Jeanne au bûcher, Didon and Enée Remebered, Barbe bleue, le Roi Carotte) and at the Saint-Etienne opera house (Fortunio, Lohengrin).
