What Inter Sign National does
Inter Sign National, LLC (ISN) is a Baltimore, Maryland-based custom architectural sign manufacturer founded in 1969 by Gilbert Bloch (originally as Maryland Stamp and Sign Company, rebranded in 1979 and later reorganized as an LLC). The company specializes in custom-made-to-order interior and exterior signage — including ADA/ANSI-compliant room and suite signs, donor recognition walls, directories, dimensional letters, plaques, and exterior signage — serving healthcare systems (MedStar, Sinai, Saint Joseph, Sheppard Pratt), universities (Johns Hopkins, Loyola Maryland, UMBC, University of Maryland), hospitality venues (Hyatt Regency, Marriott Waterfront, Renaissance, Four Seasons), corporations (T. Rowe Price, Comcast, Constellation Energy, Under Armour, McDonald's), sports (Baltimore Ravens), religious institutions, and government clients in the Baltimore/Mid-Atlantic region.
ISN operates a single Baltimore manufacturing facility running CNC routing, water jet cutting, laser cutting, UV printing, silk screening, engraving, etching, and sand blasting across materials such as acrylic, brass, aluminum, stainless steel, and solid surface substrates. The business model is sales-led and project-based: customers contact ISN via form, phone, or email, work with a dedicated salesperson, and receive a custom quote. Standard production runs 6–8 weeks with rush service available at an additional charge. Revenue is generated primarily through custom sign manufacturing, with secondary streams in design services (including a Design Build package where design fees apply toward product purchase) and installation services; the company also offers a small pandemic-protection product line (floor decals, sneezeguard panels, hand sanitizer). The firm is MBE/DBE certified in Maryland and is owned by the second-generation Lisberger family, with no external funding, no disclosed revenue, and a 1–10 employee headcount.
