What Souza, True & Partners does
Souza, True & Partners, Inc. (ST&P) is a privately held structural engineering consulting firm headquartered in Lexington, Massachusetts, founded around 1962 and operating continuously for over 62 years. The firm delivers full-service structural engineering — design, analysis, BIM modeling (Revit), peer review, structural investigations, and expert witness services — across a wide range of building types and structural materials (structural steel, reinforced and prestressed concrete, reinforced masonry, and wood). Its core service model is project-based professional consulting billed against scope, complexity, and deliverables, with revenue derived from fee-for-service engagements rather than product sales.
ST&P's go-to-market is relationship-led and B2B: the firm is engaged directly by architects, owners, developers, and contractors, primarily across the Northeast United States. All six principals (President Terry A. Louderback, in role since 1988, plus Jerome A. Yurkoski, Lisa A. Bohlin, Todd P. Blake, Martin F. Finn, and Christopher M. Motto) are working principals who are personally involved from kickoff through construction close-out — a model that differentiates the firm in institutional and complex-project work. The principals collectively hold Professional Engineer registrations in 15 U.S. states, enabling multi-jurisdiction project pursuit.
The firm's customer base is concentrated in three primary verticals — healthcare (e.g., Dartmouth-Hitchcock, Beth Israel Deaconess, Mount Auburn Hospital, Duke Cancer Center, St. Vincent Hospital), higher education and research (e.g., Smith College, Harvard School of Public Health, University of New Hampshire, Clark University), and commercial/office (e.g., Blue Cross Blue Shield, Idexx) — with secondary work in municipal/cultural, parking structures, podium/mixed-use, renovations/adaptive reuse, and schools. Marketing is primarily through project portfolio (website, Instagram, LinkedIn), direct outreach, and long-standing relationships with architecture firms; the firm has no external investors, parent company, or M&A history.
