Though Marc-André Riberdy's musical education began with the violin, he later changed his allegiance to the cello. He first studied with Father Rolland Brunelle and Sophie Coderre at the École de musique de Lanaudière, and then with Elizabeth Dolin at the Conservatoire de musique de Montréal. He did further studies in Jean-Guihen Queyras's class at the Hochschule für Musik in Freiburg, Germany.
Riberdy made a name for himself in numerous music competitions, including the Lanaudière classical music festival and competition, the Canadian Music Competition and the Hélène-Roberge Music Competition. He was also awarded a special prize at the 2016 Domnick cello competion in Stuttgart, Germany.
During his studies, Riberdy performed as a soloist with various orchestras, including the Conservatoire de musique de Montréal's string orchestra, its symphony orchestra and the Joliette Youth Orchestra. He became the Orchestre Métropolitain's associate solo cello in 2016 before before joining the NAC Orchestra's cello section in 2018. He plays a Giovanni Gagliano 1790–1800 cello with a Karl Hans Schmidt bow, both generously made available to him by Canimex.
