Valerie Guillen

Valerie Guillen serves as a key procurement professional within the W075 Endist Los Angeles office of the Department of the Army, supporting the Army’s mission to sustain and modernize critical infrastructure across military installations. She manages the acquisition of commercial and institutional construction services, heavy civil engineering works, and facility support systems essential to operational readiness. Her portfolio centers on complex, mission-critical contracts requiring coordination between design, construction, and environmental compliance, ensuring that infrastructure projects meet Army standards for safety, resilience, and long-term functionality. Guillen maintains consistent working relationships with a select group of experienced contractors including FINCANTIERI MARINE REPAIR LLC, KORTE CONSTRUCTION COMPANY, BFBC LLC, MANSON CONSTRUCTION CO, and WU & ASSOCIATES INC. These partnerships reflect a preference for vendors with proven expertise in military-grade construction, environmental remediation, and electrical systems integration. Her contracting approach emphasizes reliability, technical proficiency, and past performance, fostering long-term vendor collaboration to ensure seamless project execution across diverse operational environments. A strong advocate for small business participation, Guillen consistently prioritizes Total Small Business Set-Asides under FAR 19.5, with approximately two-thirds of her acquisitions reserved for small businesses. This pattern underscores a deliberate strategy to expand economic opportunity while leveraging the agility and specialized capabilities of small contractors in niche technical domains. Her procurement practices align with DoD socioeconomic goals, actively promoting competitive bidding among qualified small entities. Her primary procurement focus lies in NAICS 541620 (Environmental Consulting Services), reflecting a deep specialization in environmental assessments, remediation planning, and compliance support for Army installations. She also regularly procures NAICS 238210 services, overseeing electrical system installations and infrastructure upgrades. This dual technical emphasis demonstrates expertise in integrating environmental stewardship with physical infrastructure modernization to support sustained military operations.
