With the Paris Opera, Éléonore had the opportunity to perform on the stages of the Opéra Garnier and the Opéra Bastille, notably in ballets like La Fille Mal Gardée and The Nutcracker. In parallel, she continued to perfect her art by following internships in Prague, Cannes, Brittany and even Vancouver, working with Maina Gielgud, Monique Loudières, Noëlla Pontois and Violette Verdy. At 17, Éléonore decided to take additional training at the École supérieure de ballet du Québec. At the end of her three-year course, she was chosen by Les Grands Ballets to dance in The Nutcracker. She joined the company in 2016.
