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. In 1998, David took ownership of Spectrum Design Group. David loves to travel and finds design inspiration from the many countries he and his wife, Susan, have driven through on their trips to Europe. Meeting and working with new people as well as the longtime client relationships David has cultivated during his career is what makes coming to work every day so enjoyable! When he isn't at Spectrum, you'll probably find David in a kickboxing class, gardening, or spending time with his wife, daughters, and grandchildren.

Nancy has been a part of the Spectrum Design family for nineteen years. Nancy got her start in the accounting department of Spectrum Office Products after receiving her A.A.S. in Accounting. There, she worked closely with David Senise handling his budgeting and accounting needs. When David started Spectrum Design Group, Nancy became the business administrator. She now oversees all accounting, purchasing, and budgeting for Spectrum. Outside of the office, Nancy works alongside her husband, Peter, at Shamrock Hauling, LLC. When she does have some free time, Nancy loves cruising the countryside in their mustang GT convertible and spending time with her family; especially with their little granddaughter, Harper!



After 14 years in Los Angeles, Kim returned to Rochester in 2018 with her husband and two daughters. She received her BFA at RIT, her post-baccalaureate education in design and interior architecture at UCLA, and has experience designing beautiful spaces in both commercial and residential settings. She draws much inspiration from the Arts & Crafts movement in Southern California architecture, and if given the chance she’d spend days wandering the halls of the MoMA in New York. Outside of the office Kim enjoys exploring all of the area playgrounds and parks with her kids, hosting brunches at her home whenever there’s an excuse to, and traveling to new places in the U.S. and beyond. She’s so pleased to have joined the Spectrum Design team in 2019.
