Elizabeth H. Preston

Elizabeth H. Preston serves as a Contracting Officer responsible for managing complex acquisitions in support of federal operational requirements. She oversees the full lifecycle of contract actions—from market research and solicitation development to award and administration—ensuring compliance with the Federal Acquisition Regulation and agency mission objectives. Her portfolio primarily centers on information technology services and aviation support functions, with a strong emphasis on performance-based contracting and outcome-driven deliverables. Preston plays a critical role in aligning procurement strategy with operational needs, fostering transparency, and promoting efficient use of public resources. Her contractor relationships are primarily with firms specializing in computer facilities management and air transportation support services. While no single vendor dominates her award portfolio, she consistently engages with a diverse pool of qualified contractors capable of delivering scalable, secure, and mission-critical IT infrastructure and logistics support. Her approach emphasizes competitive solicitation, clear performance metrics, and vendor accountability, encouraging both large-capacity providers and agile service providers to compete on technical merit and past performance. Preston’s procurement patterns reflect a strong preference for full and open competition, with 100% of her acquisitions conducted without set-aside designations. This indicates a strategic focus on maximizing competition and selecting the most capable offerors regardless of socioeconomic status, rather than targeting specific small business categories such as 8(a), HUBZone, or SDVOSB programs. Her approach prioritizes capability and value over socioeconomic preferences, while still ensuring compliance with all applicable small business participation goals. Her primary procurement focus lies in NAICS 541513 (Computer Facilities Management Services), where she procures data center operations, cloud infrastructure support, and systems maintenance. She also frequently acquires services under NAICS 488190 (Other Support Activities for Air Transportation), including ground handling, aviation logistics, and facility support for air operations. Her technical expertise spans IT service delivery models and aviation operational support, positioning her as a specialist in mission-enabling services within highly regulated environments.
