Tiana Chandler

Tiana Chandler serves as a Contract Specialist within the Contract Administration Services Division (70RCAS) of the Department of Homeland Security’s Office of Procurement Operations, where she plays a pivotal role in executing mission-critical acquisitions that support national security and operational readiness. She manages the full lifecycle of professional, scientific, and technical service contracts, with a primary focus on administrative management consulting and computer-related services. Her work ensures the acquisition of high-integrity systems engineering, cybersecurity support, and research and development services essential to sustaining DHS’s technological infrastructure and mission-critical operations. Chandler collaborates with a diverse pool of vendors, including large professional services firms and small business contractors specializing in management consulting and IT solutions. While no single contractor dominates her portfolio, she consistently engages firms with proven expertise in federal procurement compliance, performance-based service delivery, and systems integration. Her working relationships emphasize transparency, accountability, and adherence to FAR standards, fostering long-term vendor partnerships grounded in performance metrics and risk mitigation. A strong advocate for small business inclusion, Chandler prioritizes Total Small Business Set-Asides under FAR 19.5, with 40% of her acquisitions reserved exclusively for small businesses. She actively promotes socioeconomic contracting opportunities, aligning with DHS’s mandate to increase participation from small, disadvantaged, and underserved vendors. Her procurement patterns reflect a deliberate effort to broaden the supplier base while maintaining rigorous standards for technical capability and past performance. Her primary procurement focus lies in NAICS 541611 (Administrative Management and General Management Consulting Services), where she sources strategic planning, organizational development, and process optimization services. She also regularly acquires other computer-related services under NAICS 541519, including systems analysis, IT modernization, and technical advisory support. Her domain expertise centers on enhancing operational efficiency through expert-led consulting and integrated technology solutions that advance DHS’s cybersecurity and systems engineering objectives.
