After completing his training in the finest Parisian patisseries, Yann moved to Saint Tropez to take his first position as head chef at age 21 at the Château de la Messardière, a palace hotel — where he became the pastry chef to the stars. He then went to Val d'Isère to lead the pastry team of a 5-star hotel. Seeking new challenges, he moved to Spain with his family, opened five shops, and became the Champion of Spain in artistic pieces and a finalist for the World Cup representing Spain. He captained the Spanish team in the sugar arts. Today he is an international pastry consultant and trainer, and co-founder of the World Cup of Chocolatine in Toulouse — which he has organized in China, Kazakhstan, Morocco, and Cameroon.
