What Spectrum Design Group (Senise Design Associates, Inc.) does

Spectrum Design Group (legal entity Senise Design Associates, Inc.) is a privately held, full-service interior design firm headquartered in Pittsford, New York, serving clients across the greater Rochester area. The firm was established under its current ownership in 1998 when president/owner David Senise, an NCIDQ-certified and New York State-licensed interior designer with a BFA from Syracuse University, acquired the practice from Spectrum Office Products, where he had worked in the design department since 1975. The team comprises approximately three identified professionals: David Senise, designer Kimberly Porter (BFA from RIT and post-baccalaureate at UCLA, joined 2019), and administrative support Carrie Ritter.

The firm delivers turn-key interior design services across five verticals — Corporate, Senior Living, Hospitality, Healthcare, and Residential — handling space planning, architectural and interior design elements, lighting, furnishings, fabrics, finishes, artwork, and frequently extending to exterior elements and landscaping. Its core product is the consolidated, in-house delivery of a full design package rather than any discrete software product or modular offering, and the firm works in multiple styles from traditional to contemporary without being bound to a predetermined formula.

Spectrum Design Group operates as a regional professional services firm with a consultative, direct-engagement go-to-market motion: pricing is quote-based project fees that are not publicly disclosed, and the firm relies on its Squarespace-hosted website portfolio and a Houzz professional listing for top-of-funnel visibility. It has no disclosed institutional investors, parent company, funding rounds, or M&A activity, and the operating geography is confined to the Rochester, NY market. Revenue and headcount financials are not disclosed; the firm is privately held under sole ownership of David Senise.
