David Senise, president/owner

David has been creating unique interiors for clients in the Rochester area for over forty years. David has a National Council for Interior Design Qualification certification and is a NYS licensed Interior Designer. A Syracuse native, he received his BFA in Interior Design from Syracuse University and began working in the design department at Spectrum Office Products in 1975.
