Bérénice Nuss grew up in France, near Strasbourg, the capital of Alsace. After studying piano at the Strasbourg Conservatory, she turned to the organ (studying, among others, under Johann Vexo). Until 2022, she taught at the diocesan organ school and the Maîtrise de la Cathédrale de Strasbourg, and served as organist for the Catholic parish of St-Maurice in Strasbourg. For several summers, Bérénice Nuss regularly traveled to Sainte-Anne-d'Auray (Bretagne) to participate in various music projects, including the "Soli Deo Gloria" workshop for children and young people.
From 2020 to 2026, she studied at the HMDK Stuttgart in Germany, where she completed her Bachelor's and subsequently her Master's degrees in Church Music-specializing in organ-graduating with top marks in both. During her studies, she was taught by Prof. Helmut Deutsch (organ), Prof. Denis Rouger (choral conducting), Prof. Richard Wien (orchestral conducting), and Alexander Sonderegger (piano).
Since the spring of 2026, she has served as deanery church musician and organist, playing the two historically significant organs-built by Eberhard Friedrich Walcker and the Späth brothers-at the St. Maria-Heilig-Geist Catholic parish in Schramberg. In 2025, she received the Berthold Leibinger Scholarship in recognition of her achievements.

In the realm of chamber music, he maintains a close collaboration with his brother Eduard Sonderegger (violin) in the Sonderegger Duo. Concert appearances have taken the duo to venues such as the Gasteig in Munich, the "Rising Stars" Festival in Stuttgart, and the Konzerthaus Berlin.
