After graduating from Trinity College in 1976, Kleinberg explored the New York design world while working first at Denning & Fourcade and then at Mara Palmer. His talents were further honed during sixteen-year tenure at the venerable Parish-Hadley Associates where he became Mrs. Parish’s right hand and was further mentored by Albert Hadley. Kleinberg left the firm in 1997 to start DAVID KLEINBERG DESIGN ASSOCIATES. Since then the firm has grown exponentially, servicing a roster of international clients with residences spanning the globe.

He published his monograph Traditional Now: Interiors by David Kleinberg with The Monacelli Press in 2011, a new book, David Kleinberg Interiors was recently released in March 2025.

“When looking back, our biggest compliment is the repeat business from our clients. We regularly complete several projects for each and in every case the clients are looking for something different. I strive to evolve and change direction, not to repeat,” says Kleinberg.

Kleinberg lives in New York City and East Hampton, NY. He serves on the Board of Directors of New York School of Interior Design.
