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 and employs 25, servicing a roster of international clients with residences spanning the globe.

In 2011 Kleinberg published TRADITIONAL NOW: INTERIORS BY DAVID KLEINBERG (Monacelli Press), a compendium of more than twenty residential interiors. In the same year he received the honor of being inducted into Interior Design magazine’s “Hall of Fame”. Kleinberg has been named to Architectural Digest magazine’s “The New AD 100”. He is part of Elle Décor magazine’s “A List”, which profiles 25 top designers. In addition, Kleinberg’s work appears regularly in every major design and lifestyle publication, including British House & Garden, House Beautiful, ELLE Decor, Galerie and Veranda.

“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. In Spring 2016, Kleinberg announced a corporate expansion naming three long-standing principal designers equity partners in DAVID KLEINBERG DESIGN ASSOCIATES. Those partners, listed in order of tenure include Scott Sloat, Lance Scott and Matthew Bemis.
