Olney Gleason was founded by Nicholas Olney and Eric Gleason in 2025. Across two locations in Chelsea, New York, the gallery presents exhibitions that bring international contemporary artists into dialogue with practices that have shaped the last century of art history. Spanning generations and media, the program is grounded in the gallery’s commitment to long-term artist representation and highly-researched exhibitions.

Anchored by a 3,000-square-foot main gallery illuminated by 28 skylights, the building also features a rooftop sculpture garden. In addition to its headquarters at 509 West 27th Street, Olney Gleason maintains a second space at 297 Tenth Avenue, enabling the presentation of concurrent exhibitions that support a broad range of artistic practices. The gallery regularly produces presentations at select international art fairs and in public contexts worldwide.

The gallery actively cultivates an artist-centric model and works extensively with collectors, curators and scholars to support the careers of living artists, and continues this work to advance the legacies of artists represented by its Estates & Foundations program.

The spirit of Olney Gleason’s program began to take shape in the years leading to its founding in 2025, as Nicholas Olney and Eric Gleason led the influential New York gallery Kasmin alongside executive colleagues Mariska Nietzman, Senior Partner, and Richard Buckley, Chief Operating Officer. Today, many of the relationships forged and maintained in these years remain at the heart of Olney Gleason’s core program.
