Lakeisha Thornton

Lakeisha Thornton serves as a key procurement professional within the Defense Information Systems Agency (DISA), supporting the agency’s mission to deliver secure, resilient, and interoperable information systems for global military operations. She manages a diverse portfolio of acquisitions centered on mission-critical IT sustainment, cybersecurity enablement, and cloud modernization initiatives. Her work directly supports DISA’s C4I infrastructure priorities, focusing on contracts that ensure the operational readiness of defense communications networks. Thornton routinely handles complex service-based procurements requiring high assurance standards, including systems integration, technical consulting, and spectrum management solutions, often involving multi-year task orders and indefinite-delivery/indefinite-quantity (IDIQ) vehicles. Thornton maintains a consistent working relationship with EXPRESSION NETWORKS LLC, a primary contractor supporting DISA’s IT modernization and systems engineering needs. Her procurement approach emphasizes performance-based contracting and long-term vendor partnerships, favoring firms with proven expertise in secure infrastructure deployment and enterprise IT service delivery. While she engages with a range of vendors, her pattern of repeated collaboration with EXPRESSION NETWORKS LLC suggests a strategic alignment with contractors capable of meeting DISA’s stringent cybersecurity and interoperability requirements. Her contracting activity reflects a strong preference for open competition, with 80% of awards issued without socioeconomic set-asides, indicating a focus on technical merit and capability over socioeconomic classifications. However, she maintains a deliberate 20% allocation to 8(a) competed contracts, demonstrating a measured but meaningful commitment to small business participation within the defense IT ecosystem. Thornton’s procurement focus is concentrated in NAICS 485111 (Mixed Mode Transit Systems) and 541611 (Administrative Management Consulting), which reflect her involvement in complex systems integration and enterprise-wide operational support services. She also procures specialized technical services under NAICS 541990, including cybersecurity consulting, network architecture design, and mission-critical IT sustainment. Her domain expertise lies at the intersection of defense communications infrastructure and enterprise service management, ensuring DISA’s systems remain agile, secure, and mission-ready.
