Tammie Bell

Tammie Bell supports the Telecommunications Division (HC1013) of the Defense Information Systems Agency in managing critical procurement activities that enable secure, high-capacity telecommunications infrastructure for Department of Defense operations. Responsible for executing contracts under NAICS 517121, she specializes in telecommunications reseller services that support the modernization of legacy networks, deployment of secure virtual private networks, and the enhancement of interoperable global communications. Her acquisitions directly advance DISA’s mission to sustain resilient, classified, and unclassified network capabilities across military and federal endpoints, ensuring mission-critical connectivity through commercially sourced, standards-compliant telecom solutions. Bell maintains consistent contracting relationships with a core group of established vendors including AT&T Technical Services Company, Inc., Aerospace & Commercial Technologies, LLC, Liberty Communications, Inc., AOC Connect LLC, and Norfolk Fiber, LLC. These partnerships reflect a preference for experienced providers capable of delivering turnkey telecom integration, fiber backbone services, and secure network reselling under strict DoD compliance frameworks. Her procurement approach emphasizes vendor reliability, technical compliance, and rapid scalability to meet dynamic operational demands across global theaters. Her contracting activity reflects a strong preference for open competition, with 95.5% of awards issued without set-aside restrictions, indicating a focus on performance, capability, and mission readiness over socioeconomic classifications. While small business participation is minimal at 4.5%, it is strategically aligned with Total Small Business Set-Asides under FAR 19.5, suggesting targeted opportunities for qualified firms with proven telecom delivery capacity rather than broad socioeconomic mandates. Bell’s expertise is narrowly focused on NAICS 517121, encompassing the procurement of telecommunications reselling services, including managed bandwidth, MPLS, SD-WAN, and secure transport solutions. She consistently sources services that support encrypted data transmission, network redundancy, and compliance with DoD Information Network standards, making her a key conduit for acquiring the commercial-grade telecom infrastructure that underpins modern military communications.
