Amber M. Zimmerer

Amber M. Zimmerer serves as a key procurement lead within the Telecommunications Division (HC1013) of the Defense Information Systems Agency, where she manages complex acquisitions to secure and modernize the Department of Defense’s global communications infrastructure. Her responsibilities include soliciting, evaluating, and awarding contracts for mission-critical telecom services, network modernization initiatives, and secure virtual private network deployments. She plays a central role in ensuring the resilience and interoperability of DoD communications systems by aligning procurement strategies with national security objectives and emerging technological standards. Zimmerer maintains sustained relationships with a core group of contractors 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 established vendors with proven capabilities in fiber-optic infrastructure, secure data transmission, and enterprise telecom integration. Her contracting patterns indicate a focus on long-term service delivery rather than one-time procurements, emphasizing performance-based outcomes and lifecycle support for critical network assets. Her acquisition portfolio shows a strong inclination toward open competition, with 70.8% of awards issued without set-asides, while maintaining a robust 29.2% commitment to total small business set-asides under FAR 19.5. This reflects a balanced approach that prioritizes market competition while actively fostering small business participation across the telecom and IT services sectors. Zimmerer’s primary procurement focus lies in NAICS 541519 (Other Computer Related Services) and 511210 (Data Processing and Hosting Services), underscoring her expertise in cloud-enabled communications, network management, and mission-critical IT support. She also procures specialized telecom hardware and integrated solutions under NAICS 337214 and 335999, demonstrating technical fluency across both software services and physical infrastructure domains essential to DoD’s evolving connectivity requirements.
