Shirley Castillo serves as a Contract Specialist within the Department of the Air Force’s FA4610 30 Cons Pk facility, supporting the Space Systems Command’s mission to sustain critical infrastructure at Vandenberg Space Force Base. She manages the full lifecycle of procurement actions for engineering services essential to facility modernization, utilities resilience, and technical support for national security space operations. Her portfolio focuses on complex, mission-critical contracts requiring stringent compliance with federal acquisition regulations and technical specifications for infrastructure enhancement, environmental compliance, and operational readiness. Castillo maintains consistent working relationships with a select group of specialized contractors, including MCKENZIE CONSTRUCTION & SITE DEVELOPMENT LLC for site development and civil works, DIVERSE PEST MANAGEMENT for environmental health services, TECH O. R., LLC for technical support systems, KING FREIGHT LLC for logistics coordination, and DARBONNIER TACTICAL SUPPLY LLC for specialized supply chain solutions. These partnerships reflect a preference for vendors with proven expertise in military-grade infrastructure sustainment and mission-critical service delivery, fostering long-term collaboration grounded in performance reliability and regulatory adherence. She exhibits a robust commitment to socioeconomic contracting, with 100% of her acquisitions structured as total small business set-asides under FAR 19.5. This reflects a deliberate strategy to maximize opportunities for small businesses, ensuring that qualified firms with niche capabilities in engineering and facility support can compete for and fulfill mission-critical requirements. Her contracting patterns prioritize inclusive competition while maintaining high standards of technical performance and compliance. Castillo’s procurement focus is exclusively centered on NAICS 541330 (Engineering Services), encompassing design, analysis, and technical support for aging infrastructure modernization, utilities system upgrades, and security-enabling enhancements. Her domain expertise lies in engineering solutions that ensure the operational integrity of space launch and test facilities, requiring deep familiarity with DoD standards, environmental regulations, and mission-specific technical requirements.
