Leo Spizzirri was trained by Headmaster Graziano Bertuzzo in the art and craft of making authentic Italian pizza at the Scuola Italiana Pizzaioli in Caorle, Italy. He studied under Graziano in Italy for nearly 15 years, during which he was certified in all styles of Italian pizza, as a Master (corso di alta formazione). In 2017, Leo entered the master instructor program and became an official Maestro Istruttore, one of only 100 worldwide. Although Leo is a Chicago native, he views Italy as his second home and he has spent years there studying, competing, and elevating his craft. For more than 25 years, Leo has built a reputation as a chef, master pizzaiolo, and instructor. He has been involved with local Chicago pizza operations like Giordano's Famous Stuffed Pizza and Francesca's Restaurant Group, as well as Labriola Baking Company and Bakery Cafe. Leo also launched his new restaurant Pizzeria Moderna in Austin, Texas, in early 2024.
