Robert Stewart

Robert Stewart serves as the Director of the Office of Small Business Programs at the Defense Threat Reduction Agency (HDTRA1), where he oversees the strategic integration of small business capabilities into the agency’s mission-critical procurement activities. In this role, he ensures that contracting practices align with DTRA’s mandate to counter weapons of mass destruction through advanced scientific and technical solutions. He guides the acquisition of specialized training, analytical services, and operational support systems that enhance the agency’s capacity to detect, deter, and neutralize chemical, biological, radiological, nuclear, and high-yield explosive threats. His portfolio is primarily focused on professional development and management training contracts that build workforce readiness in high-consequence threat environments. Stewart maintains enduring partnerships with leading technical and research contractors including TECHTRANS INTERNATIONAL INC, BATTELLE MEMORIAL INSTITUTE, AERIS LLC, APPLIED RESEARCH ASSOCIATES, INC., and AMAZON WEB SERVICES, INC. These relationships are characterized by long-term, performance-based engagements centered on scientific analysis, threat modeling, and digital infrastructure support. His procurement approach emphasizes technical excellence, innovation, and mission alignment, often resulting in multi-year task orders that require deep domain expertise in WMD defense and national security operations. Stewart’s contracting activity reflects a consistent preference for full and open competition, with 100% of awards issued under no set-aside categories. This underscores a strategic focus on selecting the most qualified providers—regardless of size—to ensure mission effectiveness. While small business participation is not formally set-aside, his office actively promotes outreach and mentorship to ensure capable small firms can compete for opportunities within DTRA’s technical ecosystem. The agency’s procurement activity is overwhelmingly concentrated under NAICS 611430 (Professional and Management Development Training), reflecting a core investment in workforce upskilling for complex threat response. Stewart’s team procures advanced training systems, simulation-based learning platforms, and certification programs tailored to nuclear forensics, consequence management, and interagency coordination—ensuring personnel remain proficient in rapidly evolving operational domains.
