What Caruso Turley Scott Inc. does

Caruso Turley Scott Inc. is a privately held structural engineering consulting firm headquartered in Tempe, Arizona, founded in 1963 by Sam Caruso. It is the largest structural engineering team in the Southwest, employing 51-100 professionals, of whom 52-57 are structural engineers and 70%+ hold professional engineering registrations. The firm holds licenses in all 50 U.S. states, Washington D.C., Puerto Rico, and multiple sovereign tribal nations, enabling it to serve as Structural Engineer of Record on projects of any scale within the United States.

The firm provides a full lifecycle of structural engineering services: schematic phase (systems evaluation, preliminary design, cost feasibility), design phase (structural analysis, renovations, BIM modeling using REVIT and AutoCAD, sustainable/LEED-certified design, and solar support structures), and construction phase (administration, shop drawing review, special inspections for concrete, masonry, structural steel, and post-installed anchors). It also offers municipal self-certification programs that compress permit issuance to 1-5 business days, third-party peer review, structural forensics, expert witness testimony, and seismic risk assessments. Differentiating capabilities include its self-certification and 24/7 special inspections service.

The business operates on project-based professional services fees across diversified verticals: commercial real estate, healthcare, education, hospitality and retail, government and military, industrial/manufacturing, Native American communities (via its 2021 joint venture Curley CTS), and specialty services such as adaptive reuse and solar. Go-to-market is enterprise field sales with every project personally managed by a Partner or Associate; distribution is direct to architects, developers, owners, government agencies, and tribal nations, with no resellers or intermediaries. Customer concentration is anchored on long-term relationships with branded national accounts including Walgreens (since 1992, 600+ projects), McDonald's (since 1990, 500+ projects), State Farm/Marina Heights, Banner Health, ASU, HelloFresh, City of Phoenix, and Valleywise Health, alongside tribal nation clients. Revenue is not publicly disclosed, and the firm has remained an independent partnership with no external capital or parent company.
