Doris R. Castro serves as Supervisory Contracting Officer at Naval Facilities Engineering Systems Command (NAVFAC) Marianas, where she oversees the planning, solicitation, and award of complex construction, engineering, and environmental support contracts critical to military readiness across Guam, the Northern Mariana Islands, and the Federated States of Micronesia. In this leadership role, she ensures compliance with federal acquisition regulations while advancing NAVFAC’s mission of resilient infrastructure development and environmental stewardship. Her portfolio primarily includes high-stakes, mission-critical acquisitions in specialty trade contracting, environmental consulting, and building construction, requiring rigorous technical evaluation and risk mitigation strategies. Ms. Castro maintains consistent working relationships with key contractors including SEL Engineering Services, Inc., Schneider Electric Buildings Critical Systems, Inc., CDM Constructors Inc., and AMD International Technologies LLC, reflecting a preference for established vendors with proven expertise in defense infrastructure and critical systems. Her contracting approach emphasizes performance-based outcomes, technical proficiency, and long-term operational sustainability, fostering collaborative partnerships with firms capable of delivering integrated facility solutions under demanding operational conditions. Her procurement strategy demonstrates a strong commitment to socioeconomic diversity, with nearly 60% of her acquisitions structured as set-asides for small businesses, including HUBZone, Service-Disabled Veteran-Owned Small Business (SDVOSB), and 8(a) programs. This reflects a deliberate effort to expand opportunities for underrepresented businesses while maintaining competitive rigor and mission alignment across all award decisions. Ms. Castro’s technical focus centers on NAICS 238990 (All Other Specialty Trade Contractors) and 541620 (Environmental Consulting Services), with significant activity in commercial building construction, electrical systems, and painting and wall covering. Her expertise lies in managing complex, multi-disciplinary projects that require coordination between environmental compliance, facility modernization, and infrastructure resilience—ensuring NAVFAC Marianas meets its operational and sustainability objectives through strategic, compliant contracting.
