She did her master's degree with honor at ESAIL in Lyon, and after several experiences with architects and working in different studios, her passion for Art & Architecture has increased further.

Anthony has around 7 years of professional experience in architecture, furniture and interior design. He worked in London at STAC Architecture and NLS Architecture where he was in charge of several retail and residential projects in the UK and around the world. After all the experience built in several studios, such as the award-winning Chartier Dalix in Paris, he founded the MAS studio in 2018 together with Marianne, whose skills perfectly match his own.
