Before joining Compass, Marion worked with one of the top teams at Douglas Elliman, where she was recognized as a 2024 Rising Star. Prior to her career in real estate, she practiced law at Sullivan & Cromwell LLP in both Paris and New York, advising clients on mergers, acquisitions, capital markets transactions, and white-collar litigation.

She holds an MBA degree from ESSEC Business School, a J.D. in Business Law from University Paris-Assas as well as the Paris Bar.

Originally from France, Marion's passion for real estate and design was shaped by growing up in a family of architects and living in iconic buildings designed by Le Corbusier and Georges-Eugène Haussmann. Now a proud New Yorker, she appreciates the city's rich architectural heritage, from the classic designs of Rosario Candela to the modern luxury of new developments. Having owned and renovated properties in both Paris and New York City, she brings a discerning eye to every transaction, helping clients optimize both value and lifestyle.
