Tillotson Design Associates, founded in 2004, is a WBE lighting design consultancy based in New York City. A diverse staff with backgrounds in architecture, interior design, and theater, including several LEED accredited professionals, combine talents to create exemplary work. Together, our three principals provide over 75 years of lighting expertise. The launch of Tillotson Design Associates came just after Ms. Tillotson completed lighting designs for the Seattle Central Public Library and Prada Beverly Hills with the Office for Metropolitan Architecture, and the Rubin Museum of Art with Imrey Culbert. Collaborating with developers, architects, and interior designers throughout the world, our diverse portfolio includes interior and exterior lighting for corporate headquarters, universities, hotels, libraries, museums, parks, performance halls, residences, restaurants, and retail establishments.

Our passion for design excellence, meticulous attention to detail, and heavy principal involvement from concept to final focusing contributes to our success. Our hands on process, extensive research, and team oriented approach allow us to look at lighting challenges in a fresh and unique way. We are not limited by what has been built before. We welcome new challenges and enjoy the investigation and research of unique materials and ideas. We present solutions yet encourage collective decision making by the entire design team and client.
