Galby J Celestin

Galby J. Celestin serves as a Contract Specialist within the Department of the Air Force under FA4484, responsible for managing the acquisition of mission-critical infrastructure and operational support services essential to air base readiness. His role encompasses the full lifecycle of procurement—from market research and solicitation development to contract award and administration—ensuring compliance with federal regulations and alignment with Air Force infrastructure modernization goals. He primarily handles construction, facility maintenance, and air transportation support contracts, with a strong emphasis on sustaining airfield operations, environmental compliance, and facility modernization initiatives. Celestin maintains consistent working relationships with a core group of experienced contractors, including PAETZOLD CONSTRUCTION CO INC, SEQUOIA CONSTRUCTION INCORPORATED, RANCO CONSTRUCTION INC, THE PASSANANTE GROUP, LLC, and XENTURIS LLC. These partnerships reflect a preference for firms with proven expertise in military installation work, heavy civil construction, and technical support services. His contracting approach emphasizes reliability, regulatory adherence, and performance-based outcomes, fostering long-term vendor collaboration grounded in accountability and mission alignment. A dedicated advocate for small business participation, Celestin consistently applies Total Small Business Set-Asides and HUBZone Set-Asides, each at 50% of eligible procurements. This reflects a deliberate strategy to expand economic opportunity for historically underutilized businesses while ensuring access to qualified, geographically targeted contractors with deep community knowledge. His socioeconomic contracting patterns prioritize HUBZone-certified firms, reinforcing both mission effectiveness and national socioeconomic objectives. His primary procurement focus centers on NAICS 488190 (Other Support Activities for Air Transportation) and 237310 (Highway, Street, and Bridge Construction), underscoring expertise in airfield ground support systems, runway maintenance, and base infrastructure upgrades. He specializes in acquiring services related to HVAC, electrical systems, utilities, and transportation network enhancements critical to sustaining operational readiness across Air Force installations.
