Billy W. Castleberry serves as a Contract Specialist responsible for managing the full lifecycle of federal acquisitions, from requirements validation and market research through solicitation, evaluation, award, and contract administration. He plays a critical role in ensuring compliance with the Federal Acquisition Regulation (FAR) and supports the agency’s mission by delivering mission-critical services through transparent, competitive procurement processes.

Castleberry cultivates collaborative relationships with a diverse array of vendors, including management consulting firms, voluntary health organizations, and social advocacy groups.

His approach emphasizes fair competition and clear performance metrics, fostering long-term vendor partnerships grounded in accountability and compliance. A strong advocate for small business participation, Castleberry prioritizes Total Small Business Set-Asides under FAR 19.5, with 40% of his acquisitions reserved exclusively for small businesses. His contracting patterns reflect a deliberate commitment to socioeconomic goals, regularly utilizing set-asides to expand opportunities for small, woman-owned, and minority-owned firms, while maintaining a balanced 60% open competition stream to ensure market-wide access and value. His primary procurement focus centers on NAICS 541611 for administrative and general management consulting services, and NAICS 813212 and 813319 for voluntary health and social advocacy organizations. He specializes in acquiring strategic advisory services, program design, stakeholder engagement, and policy implementation support, demonstrating deep technical familiarity with nonprofit operational models and public-sector service delivery systems.
