A dancer from an early age, Eleonora Campello trained in classical technique at the Il Balletto school in Castelfranco, Italy, directed by Susanna Plaino. At the age of 18, she joined the Ballet Junior de Genève. The professional training she received there enabled her to broaden her practice to include contemporary dance, improvisation and yoga. In this context, she took part in new works and revivals of the repertoire, working with Marcos Morau, Noa Zuk, Barak Marshall, Jan Martens and Hofesh Shechter. She joined the Lyon Opera Ballet in the summer of 2022.
