He manages the full lifecycle of construction and facility services contracts, with a primary focus on plumbing, heating, and air-conditioning systems essential to base resilience.

Castillo maintains a consistent and trusted partnership with ALTUS TECHNICAL SOLUTIONS LLC, a key contractor specializing in integrated facility services for defense infrastructure. His contracting patterns reflect a preference for long-term, performance-based engagements with vendors capable of delivering complex, technical solutions under tight operational timelines. He collaborates closely with technical stakeholders to define performance requirements and ensure contractor accountability through robust contract administration practices, including change order management and quality assurance oversight. A staunch advocate for small business participation, Castillo administers 100% of his acquisitions under the Total Small Business Set-Aside provision (FAR 19.5), ensuring that all contract opportunities are reserved exclusively for small businesses. This reflects a deliberate and sustained commitment to socioeconomic contracting goals, fostering equitable access to defense contracting for small, locally-based firms with the technical capacity to deliver mission-critical facility services.

He procures turnkey solutions for HVAC retrofits, ductwork installation, chilled water systems, and climate control infrastructure, requiring expertise in ASHRAE standards, energy efficiency mandates, and DoD facility sustainment protocols. His domain expertise ensures that all acquisitions meet rigorous operational and environmental compliance standards.
