Drawn to the legal profession from an early age—and particularly to its ethical principles of independence and compassion—it was only natural for Marc-Antoine to start his own law firm so he could work closely with his clients on a daily basis.

Previously, Marc-Antoine worked for several years as an attorney in the Life Sciences department at Dentons (formerly Salans), notably alongside Pascale Poupelin and François Vignaud, where he strengthened his skills and industry expertise.

From the start of his career, Marc-Antoine focused on the life sciences practice at René Descartes University—Paris 5, where he earned a Master 2 in health products law, and gained extensive experience at several leading law firms specializing in health law (Jasper (formerly Vatier), UGGC&Associés, Simmons & Simmons LLP), the public health division of the Paris District Court (investigations), and Leem (a professional organization representing the pharmaceutical industry in France).

Marc-Antoine speaks French and English.
