Geoffrey Diner Gallery

Backed by four decades of working with private collectors and institutions, the gallery deals in high-caliber decorative design and modern art. Its inventory bridges twentieth-century fine art and design, bringing together works by Helen Frankenthaler, Hans Hofmann, and Lee Mullican alongside pieces by Émile-Jacques Ruhlmann, Gio Ponti, and Marc Newson. Beyond Washington, the gallery operates viewing spaces in New York and London, exhibits at international fairs including TEFAF New York, and provides professional appraisal services for estates and collectors.
