Robin Castoldi

Robin Castoldi serves as a Contracting Officer within Washington Headquarters Services (WHS), part of the Department of Defense, where she manages a diverse portfolio of professional services acquisitions critical to the modernization and operational efficiency of defense enterprise functions. Her responsibilities include full lifecycle contract administration—from solicitation and evaluation to award and closeout—for mission-critical administrative, technical, and consulting services that support DoD-wide institutional transformation. She specializes in procurement actions under the Federal Acquisition Regulation (FAR), with a focus on performance-based contracting and service-based deliverables that align with WHS’s strategic priorities in digital transformation and resource optimization. Castoldi maintains consistent working relationships with a core group of established contractors, including CLARITY INNOVATIONS LLC, CYNERGY PROFESSIONAL SYSTEMS LLC, SIGNATURE RENOVATIONS LLC, AMD INTERNATIONAL TECHNOLOGIES LLC, and GUIDEHOUSE INC. These partnerships reflect a preference for firms with demonstrated expertise in systems modernization, operational consulting, and technical support services. Her contracting patterns indicate a reliance on repeat vendors with proven performance histories, fostering long-term collaboration grounded in compliance, accountability, and mission alignment. Her set-aside preferences show a strong emphasis on open competition, with 81.8% of awards issued without socioeconomic set-asides. The remaining 18.2% are awarded under Total Small Business Set-Aside authorities (FAR 19.5), demonstrating a measured but intentional commitment to small business participation without compromising acquisition flexibility or mission readiness. Castoldi’s procurement activity is concentrated in NAICS 541712 (Research and Development in Physical, Engineering, and Life Sciences) and 541519 (Other Computer Related Services), each accounting for one-third of her portfolio. She also regularly procures administrative and technical consulting services under NAICS 541611 and 541690, reflecting expertise in enterprise systems support, data analytics, and defense infrastructure optimization. Her work centers on securing high-impact professional services that enable DoD components to operate more efficiently through innovation and integrated technical solutions.
