Kiersten Vanderhoof

Kiersten Vanderhoof serves as a Purchaser within the Finance Agency of Washington County, Oregon, where she plays a critical role in executing procurement activities that uphold the agency’s mission of fiscal integrity and public accountability. Responsible for managing competitive solicitations and contract administration, she ensures compliance with state and federal procurement regulations while supporting the county’s financial oversight functions. Her acquisitions primarily support infrastructure, engineering, and environmental services essential to maintaining public financial transparency and operational efficiency. While no specific contractor relationships are currently documented, Vanderhoof engages with a broad spectrum of qualified vendors, including engineering firms, environmental consultants, and construction contractors, typically through sealed bid and request for proposal processes. Her procurement approach emphasizes competitive fairness, documentation rigor, and vendor performance accountability, fostering transparent and repeatable vendor partnerships grounded in compliance and value delivery. Vanderhoof’s contracting patterns reflect a strong preference for open competition, with 100% of her acquisitions designated as “No Set-Aside,” indicating a focus on full and open competition without socioeconomic set-asides such as 8(a), HUBZone, or SDVOSB programs. This approach aligns with the agency’s emphasis on technical merit and cost-effectiveness over socioeconomic targeting, though it does not preclude participation from small businesses that compete on equal footing. Her primary procurement focus lies in NAICS 237310 (Highway, Street, and Bridge Construction), followed by engineering services (541330) and environmental consulting (541620). She routinely procures civil infrastructure design, geotechnical assessments, and regulatory compliance services, demonstrating deep familiarity with public works procurement standards and the technical requirements of capital improvement projects supporting county financial operations.
