Aaron Castillo

Aaron Castillo serves as a key procurement lead within the FA4613 90 Cons Pk unit of the Department of the Air Force, responsible for managing mission-critical infrastructure sustainment contracts that support nuclear deterrence operations. He oversees the acquisition of specialized construction and facility maintenance services essential to the operational integrity of remote missile fields and launch facilities, ensuring compliance with stringent defense standards. His portfolio centers on long-term sustainment, modernization, and resilience upgrades to critical defense infrastructure, requiring precise adherence to federal acquisition regulations and security protocols. Castillo maintains consistent working relationships with a select group of specialized contractors, including Olgoonik Specialty Contractors, LLC, Aerospace & Commercial Technologies, LLC, and SafeWare Inc., each recognized for their expertise in defense-adjacent construction, security systems, and facility maintenance. These partnerships reflect a preference for vendors with proven experience in remote, high-security environments and the ability to operate under strict operational tempo requirements. His contracting approach emphasizes reliability, technical proficiency, and mission alignment over volume, fostering long-term vendor collaboration. He maintains a 100% small business set-aside policy across all procurements under his purview, fully aligning with FAR 19.5 and prioritizing socioeconomic programs that enhance industry diversity and regional economic resilience. This reflects a deliberate strategy to empower small businesses with niche capabilities in defense infrastructure, particularly those certified under HUBZone, 8(a), or SDVOSB programs. Castillo’s procurement focus is concentrated in two primary NAICS categories: 238220 (Plumbing, Heating, and Air-Conditioning Contractors) and 314110 (Carpet and Rug Mills), representing his agency’s dual emphasis on climate-controlled facility systems and specialized interior finishes for secure, low-signature environments. His technical expertise lies in procuring mission-specific building systems that meet DoD environmental, safety, and electromagnetic interference standards, ensuring both operational functionality and long-term durability in austere locations.
