Marie Chastagnol attended the National School of Violin-making in Mirecourt, France, for three years. While studying there, she spent a few weeks in the workshop of Jean-Frédéric Schmitt in Lyon and with Arthur Dubroca and Alexandre Aumont in Paris. There she made her first steps in bow-making. After passing her degree at Mirecourt in 2007, she worked for four years in the workshop of Yannick Le Canu in Lille. After that, she was employed as a bow-maker by Olivier Pérot in his Montreal, Canada, workshop. In 2013, she started to work with Georges Tépho, in Quimper, France. In 2017, she decided to create her own workshop in Quimper when Georges Tépho moved to Paris. She carries on working with bow-makers like Eric Fournier and Emmanuel Bégin to refine her technique.

the Collectif de Lutherie et d’Archèterie Comtemporaines (CLAC).
