Tammie Allen

Tammie Allen serves as a Purchasing Agent for the Defense Threat Reduction Agency (HDTRA1), where she plays a critical role in executing mission-critical acquisitions to counter weapons of mass destruction and emerging national security threats. She manages a diverse portfolio of contracts supporting scientific research, technical analysis, and operational capabilities in chemical, biological, radiological, nuclear, and high-yield explosive defense domains. Her acquisitions typically involve advanced detection systems, forensic analysis tools, threat intelligence platforms, and secure computing infrastructure, ensuring the agency maintains technological superiority in high-consequence environments. Allen maintains consistent procurement relationships with leading technical contractors including TECHTRANS INTERNATIONAL INC, BATTELLE MEMORIAL INSTITUTE, AERIS LLC, APPLIED RESEARCH ASSOCIATES, INC., and AMAZON WEB SERVICES, INC. These partnerships reflect a strategic emphasis on integrating cutting-edge R&D, specialized engineering services, and cloud-based data processing solutions. Her working patterns favor long-term, performance-based contracts with firms possessing deep domain expertise in defense science and secure infrastructure, often leveraging indefinite-delivery/indefinite-quantity (IDIQ) mechanisms to ensure responsive capability deployment. Allen demonstrates a balanced commitment to socioeconomic contracting, with approximately half of her acquisitions set aside for small businesses under FAR 19.5, and the other half conducted as full and open competitions. This approach ensures broad vendor participation while maintaining access to specialized capabilities only available through larger, established contractors. Her procurement strategy actively supports small business growth without compromising mission readiness. Her primary NAICS focus areas include 511210 (Software Publishers) for threat modeling and data analytics tools, 334519 for custom sensing and monitoring devices, and 518210 for secure computing and cloud hosting services. She routinely procures advanced instrumentation, fabricated metal components for ruggedized systems, and mission-specific IT infrastructure, reflecting deep technical expertise in defense science and secure digital environments.
