Tiffany Haselhorst

Tiffany Haselhorst supports the Telecommunications Division (HC1013) of the Defense Information Systems Agency in managing critical telecommunications and information technology acquisitions that underpin the Department of Defense’s global communications infrastructure. She is instrumental in procuring services that modernize legacy telecom systems, deploy secure virtual private networks, and ensure interoperable, high-capacity connectivity across military and federal operations. Her procurement portfolio centers on professional, scientific, and technical services essential to sustaining and expanding DISA’s mission-critical networks, with a focus on secure, scalable, and resilient digital infrastructure. Haselhorst maintains consistent contracting relationships with leading 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 established vendors with proven expertise in secure network engineering, fiber optic deployment, and mission-critical systems integration. Her contracting patterns indicate a reliance on firms capable of delivering complex, high-assurance telecom solutions under stringent DoD security and compliance standards. Her acquisition strategy prioritizes open competition, with 85.7% of contracts issued without set-aside designations, reflecting the technical complexity and scale of requirements that often necessitate large-capacity vendors. Nevertheless, she maintains a meaningful commitment to small business participation, with 14.3% of awards directed under Total Small Business Set-Asides, consistent with FAR 19.5 guidelines and aligned with broader DoD socioeconomic objectives. Her primary NAICS focus areas include Other Computer Related Services (541519) and Research and Development in the Physical, Engineering, and Life Sciences (541712), underscoring her expertise in procurement of advanced networking technologies, systems engineering, and technical R&D services. She also regularly acquires Computer Facilities Management Services and Engineering Services, demonstrating deep domain knowledge in secure infrastructure operations and telecommunications systems integration.
