Mary Ann Hall

Mary Ann Hall supports the Telecommunications Division (HC1013) of the Defense Information Systems Agency in managing critical procurement activities that sustain and modernize the Department of Defense’s global communications infrastructure. She is responsible for executing complex acquisitions of secure telecommunications services, network modernization solutions, and mission-critical IT support systems. Her work directly enables resilient, high-capacity connectivity across military and federal operations, with a focus on transitioning legacy systems to secure, scalable virtual private networks and interoperable cloud-enabled platforms. She handles full lifecycle contracting actions under FAR and DFARS guidelines, ensuring compliance with national security standards and operational readiness requirements. Hall maintains established relationships with leading telecommunications and IT services providers, 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 vendors with proven expertise in secure fiber-optic deployment, encrypted network services, and DoD-compliant infrastructure integration. Her contracting approach emphasizes performance-based outcomes, technical interoperability, and long-term service sustainment, fostering collaborative vendor engagement grounded in mission-critical reliability. Her procurement portfolio reflects a balanced commitment to socioeconomic goals, with equal portions of awards directed toward total small business set-asides and 8(a) competed contracts, alongside a significant share of open, unrestricted acquisitions. This pattern demonstrates a deliberate strategy to foster competition while ensuring robust participation from small, disadvantaged, and service-disabled veteran-owned businesses, aligning with federal mandates and DISA’s broader diversity objectives. The division’s sole NAICS focus—541519 (Other Computer Related Services)—indicates her specialization in non-hardware IT services, including network architecture design, secure data transport, cybersecurity-integrated telecom support, and systems integration for distributed command environments. She consistently procures mission-enabling services that enhance the agility, security, and resilience of the DoD’s global communications architecture.
