Maroussia started dancing at the Conservatoire populaire de Genève and then continued at Studio des bains where she began pre-professional training in Contemporary. In 2008, she joined the formation-company Marchepied (Lausanne) led by Nicolas Pettit and Corinne Rochet.
In parallel to her training in contemporary dance, Maroussia practices Hip-Hop, and more specifically Popping.
