Specializing in townhouses and new development condominiums on the Upper East Side and Upper West Side, Marion is known for her exceptional work ethic, refined taste in design and renovation, and her dedication to negotiating the best deals for her clients.

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 in both Paris and New York, advising clients on mergers, acquisitions, capital markets transactions, and white-collar litigation.

Originally from Provence, 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.
