What GSB does

GSB, Inc. Architects & Planners is a privately held architecture firm founded in 1979 by Ronald G. Smith and headquartered at 3555 NW 58th St, Suite 700W, Oklahoma City, Oklahoma. Over a 46-year operating history, the firm has developed a portfolio concentrated in luxury hospitality and resort architecture, with repeat engagements for enterprise clients including Marriott International, Walt Disney World/Disney Vacation Club, Ritz-Carlton, Caesars Palace, St. Regis, and the St. Joe Company. The firm also serves civic (Oklahoma City Public Schools), educational (University of Oklahoma), banking (First Fidelity Bank), and senior-living clients, providing some non-hospitality diversification. GSB's geographic reach is national across the United States and extends to the Caribbean, despite the single Oklahoma City headquarters.

The firm offers a comprehensive suite of professional architectural services: architecture, interior design, master planning, programming, feasibility studies, facility evaluation, sustainable design/LEED, rendering/visualization, construction drawings, construction specifications, construction contract administration, Building Information Modeling (BIM), bond issue assistance, and storm-hardened shelters. Underlying production technology centers on REVIT-based BIM, supported by proprietary firm-wide Revit standards for design and construction documentation. Sustainable design is embedded in standard practice rather than offered as an add-on, with LEED-certified project experience including the OU Radar Innovations Laboratory.

GSB generates revenue through negotiated, project-based professional service fees billed against scope-defined engagements, often spanning multi-year timelines. The firm operates as Architect of Record, Design Architect, or full-service provider depending on client need. Client acquisition is direct, driven by business development, long-term enterprise relationships, and reputation-based referrals rather than broad marketing campaigns. The firm is privately held, founder-controlled, and independent with no parent company, no funding rounds, and no identified M&A activity; revenue is not publicly disclosed.
