Mary Hallam

Mary Hallam serves as a Contracting Officer within the Contracting and Procurement office of the Transportation Security Administration under the Department of Homeland Security, where she leads the acquisition of critical transportation security technologies and support services. Her portfolio centers on procuring advanced detection systems, cybersecurity solutions, and operational infrastructure for aviation and transit environments, including explosive detection equipment, irradiation apparatus, and GPS-enabled rail monitoring systems. She ensures compliance with federal acquisition regulations while aligning procurements with the agency’s mission to enhance national transportation security through innovative, reliable, and scalable solutions. Hallam cultivates strategic partnerships with a diverse range of vendors, primarily engaging firms specializing in computer-related services, data infrastructure, and technical consulting. While no single contractor dominates her award portfolio, she consistently collaborates with firms capable of delivering complex, mission-critical IT and systems integration services, often requiring stringent security clearances and compliance with NIST and FISMA standards. Her contracting approach emphasizes performance-based outcomes, risk mitigation, and vendor accountability across the lifecycle of each acquisition. Her set-aside preferences reflect a strong commitment to small business participation, with 14.3% of her acquisitions designated as total small business set-asides under FAR 19.5. Although the majority of her contracts remain open competition, she actively encourages small business engagement through targeted outreach and clear solicitation language that supports eligibility for SBA programs, including HUBZone and SDVOSB certifications, aligning with broader DHS socioeconomic goals. Hallam’s procurement focus is heavily concentrated in NAICS 541519 (Other Computer Related Services), reflecting her dominance in acquiring custom software development, systems integration, and cybersecurity support. She also regularly procures computing infrastructure services (NAICS 518210), office equipment leasing (NAICS 532420), and human resources consulting (NAICS 541612), demonstrating expertise in both technical and administrative support domains essential to modernizing TSA’s operational capabilities.
