What TSP does
TSP, Inc. is a 100% employee-owned (ESOP) multidisciplinary architecture, engineering, planning, and interior design firm headquartered in Sioux Falls, South Dakota. Founded in 1930 by Harold Spitznagel, the firm operates four offices across the Upper Midwest — Sioux Falls SD (headquarters), Rapid City SD, Rochester MN, and Watertown SD — and serves institutional clients in education (K-12 and higher education), healthcare, community/civic, and commercial sectors. The firm delivers integrated services under a single practice: architecture (pre-design through construction administration), in-house mechanical/electrical/structural/technology engineering, master and facility planning, and interior design with FF&E coordination. Named clients include Mayo Clinic, Sanford Health, Monument Health, South Dakota State University, Augustana University, Montana State University, the City of Sioux Falls, the City of Rochester, the U.S. Department of Veterans Affairs, and First National Bank, with project work extending into Colorado, North Carolina, South Carolina, and Oregon beyond the core regional footprint.
TSP makes money through project-based professional services fees billed on a project-by-project basis, with pricing driven by scope, complexity, and client requirements rather than standardized rate cards. The go-to-market model is direct enterprise engagement via relationship-driven business development, RFPs, RFQs, and referrals — no resellers or intermediaries are used. Marketing is concentrated in a content-driven digital presence (teamtsp.com, TSP Talk blog, LinkedIn, Facebook, Instagram, YouTube, X/Twitter) supplemented by AIA conference participation and university career fair recruiting. The technology stack consists of industry-standard Building Information Modeling (BIM) and 3D visualization tools; the firm does not operate a proprietary software platform or technology product. Competitive positioning rests on 95 years of regional operating history, deep institutional client relationships, in-house multidisciplinary integration that reduces coordination friction, and an employee-ownership culture recognized by six consecutive years on Prairie Business's '50 Best Places to Work' list and the AIA Minnesota Emerging Professional Friendly Firm award. The firm is privately held under South Dakota governing law and is entirely employee-owned with no external parent, institutional investor, or public-market exposure.
