Preston oversees the full lifecycle of acquisitions—from market research and solicitation development to contract award and administration—ensuring alignment with federal mandates and agency objectives. While specific contractor relationships are not publicly detailed, her procurement patterns indicate a preference for open competition, with the vast majority of awards issued under non-set-aside mechanisms. She engages with a broad spectrum of vendors, including large primes, mid-tier contractors, and small businesses, fostering transparent and equitable procurement practices. Her approach emphasizes performance-based contracting and rigorous source selection criteria to ensure quality, timeliness, and fiscal accountability. Preston demonstrates a targeted commitment to small business participation, with approximately 10.7% of her awards directed toward 8(a) competed contracts. Though set-asides represent a minority of her portfolio, her consistent use of 8(a) opportunities reflects a deliberate effort to promote socioeconomic equity and expand the pool of qualified small business vendors. She adheres to federal small business goals while maintaining a strong emphasis on full and open competition as the default procurement pathway. Her primary technical focus lies in NAICS 813110 (religious organizations), 236220 (commercial and institutional construction), and 488190 (air transportation support), indicating expertise in facility-related services, construction management, and logistics support for aviation infrastructure. She routinely procures design-build services, facility maintenance, training programs, and specialized electrical components, demonstrating deep familiarity with construction standards, operational support systems, and mission-critical supply chains.
