THE THERRIEN COMPANY INC.

The Therrien Company Inc. specializes in providing independent real estate appraisal services for federal properties, delivering compliant, defensible fair market value estimates in accordance with the Uniform Standards of Professional Appraisal Practice (USPAP). Their core expertise lies in conducting comprehensive residential and commercial property appraisals for government-owned facilities, including military installations and federal infrastructure. They apply rigorous analytical methodologies, including sales comparison, cost, and income approaches, while ensuring adherence to federal appraisal guidelines and documentation standards. Their work supports acquisition, disposal, and asset management decisions by producing technically sound, audit-ready appraisal reports that meet federal regulatory requirements. Key differentiators include precision in site-specific valuation analysis, familiarity with federal property use cases, and strict compliance with appraisal ethics and reporting protocols. The company maintains a consistent working relationship with the General Services Administration, providing appraisal services for Army Reserve Centers and other federal real estate assets. Their engagements typically involve high-stakes valuations for properties undergoing federal acquisition or disposition, indicating a trusted, repeat partnership rooted in reliability and regulatory precision. Their primary industry focus is on NAICS 531320, which encompasses professional real estate appraisal services for public sector clients. This positions them as a niche provider within the federal real estate valuation market, specializing in government-owned properties rather than private-sector residential or commercial appraisals. Their vertical specialization is in defense and federal infrastructure assets, distinguishing them from generalist appraisal firms. The Therrien Company Inc. is a small, locally based firm headquartered in Kenmore, Washington, operating as a sole proprietorship or small business under the 2L entity structure. While they hold no formal government certifications, their consistent performance on federal contracts demonstrates a proven ability to meet stringent federal appraisal standards. Their geographic presence is focused on the Pacific Northwest, with a market positioning centered on delivering high-integrity appraisal services to federal agencies managing real property portfolios.
