What Twin Peaks does
Twin Peaks Testing is a privately held professional services firm headquartered in Long Island City, NY, founded in 1992 by Jerry Agajian. The firm provides construction materials testing, non-destructive testing (NDT), and special inspections services to commercial construction projects and government infrastructure clients across the New York and New Jersey markets. Its stated scale includes 150+ technical professionals, 101-250 total employees, and a cumulative track record of 10,000+ projects completed since inception.
The core service offering is built around certified inspection and testing workflows required by NYC and NJ building codes and by municipal infrastructure specifications. Deliverables include special inspections mandated under the NYC Building Code, laboratory and field testing of construction materials (concrete, steel, soils, etc.), and NDT methods. Customers are predominantly public agencies — notably the Port Authority of New York and New Jersey, NYC agencies, and NYS agencies — alongside major private general contractors such as SKANSKA and Jacobs. The firm's value proposition rests on its certified workforce, multi-decade operating history, and relationships with regulated public-sector buyers.
The business model is professional services on a quote/project basis: revenue is generated per engagement, with pricing reflecting scope, required certifications, and prevailing wage/labor rates in the NY/NJ market. There is no indication of recurring SaaS, subscription, or productized revenue. The firm is privately held with no disclosed outside funding, M&A activity, or leadership transitions beyond the founder, and recently faced a federal sexual harassment lawsuit that introduces reputational and legal exposure. Geographic scope remains the NY/NJ metro, with no documented expansion into adjacent states or verticals.
