S. Andrew Whittaker

Andrew Whittaker serves as a key procurement professional within the Cwmd Acq Division of the Department of Homeland Security’s Office of Procurement Operations, where he supports the acquisition of critical technologies designed to detect, monitor, and respond to radiological, nuclear, and high-consequence threats. His responsibilities center on managing complex contracts for personal radiation detectors, mobile monitoring systems, and medical surveillance platforms used by first responders and public safety personnel. He operates within a mission-critical framework that demands rapid, secure, and technically rigorous procurement processes aligned with federal acquisition regulations and national security priorities. Whittaker cultivates strategic relationships with a diverse pool of vendors specializing in advanced sensing technologies, engineering services, and scientific research. While no single contractor dominates his portfolio, he consistently engages firms with proven expertise in radiation detection hardware, field-deployable analytics, and compliance-driven system integration. His contracting approach emphasizes technical capability over volume, favoring vendors with demonstrated experience in DoD and DHS environments and robust quality assurance protocols. His procurement patterns reflect a strong preference for open competition, with 80% of acquisitions conducted without set-asides. However, he maintains a deliberate 20% commitment to total small business set-asides under FAR 19.5, ensuring opportunities for small, innovative firms to contribute to national resilience efforts. This balance supports both scalability and socioeconomic goals without compromising mission readiness. Whittaker’s primary NAICS focus areas include research and development in physical and life sciences, professional organizations supporting technical standards, and heavy civil engineering for specialized infrastructure. He routinely procures advanced detection systems, data analytics platforms, and field-deployable medical response tools, demonstrating deep expertise in radiological safety technology, sensor integration, and emergency response systems. His work bridges scientific innovation with operational readiness in high-stakes public safety domains.
