Shirley Castillo serves as a Contract Specialist within the Space Systems Command’s FA4610 30 Cons Pk facility, responsible for managing the full lifecycle of procurement actions to sustain critical infrastructure at Vandenberg Space Force Base. Her work directly supports national security space operations by acquiring essential services that maintain facility integrity, utilities resilience, and technical readiness. She specializes in engineering services contracts under FAR Part 15, managing complex requirements for facility modernization, environmental compliance, and mission-critical support systems. Her portfolio is tightly aligned with the agency’s strategic imperative to modernize aging infrastructure while ensuring operational continuity for launch and test missions. Castillo maintains consistent working relationships with a core group of contractors including MCKENZIE CONSTRUCTION & SITE DEVELOPMENT LLC, DIVERSE PEST MANAGEMENT, TECH O. R., LLC, and DARBONNIER TACTICAL SUPPLY LLC. These partnerships reflect a focus on integrated facility support—ranging from site development and pest control to specialized technical and logistics services. Her contracting approach emphasizes performance-based outcomes, with an emphasis on quality assurance and compliance with DoD infrastructure standards. She fosters long-term vendor relationships built on reliability, technical proficiency, and adherence to safety and security protocols critical to space operations. Her procurement patterns show a balanced commitment to socioeconomic goals, with one-third of her awards structured as Total Small Business Set-Asides under FAR 19.5, reflecting a deliberate effort to expand opportunities for small businesses. While the majority of her acquisitions remain open to all competitors, her consistent use of small business set-asides underscores a proactive approach to fostering competition and workforce development within the defense industrial base. Castillo’s acquisitions are exclusively focused on NAICS 541330 (Engineering Services), underscoring her specialization in technical engineering support for facility sustainment. She procures services such as structural assessments, electrical and mechanical system upgrades, environmental remediation, and mission-critical infrastructure design—domain expertise essential to maintaining the operational resilience of space launch and test facilities.
