Adrianne M. Callihan

Adrianne M. Callihan serves as a Small Business Specialist, dedicated to advancing equitable access to federal contracting opportunities within general government support services. In this role, she provides strategic guidance to procurement teams on small business outreach, socioeconomic program compliance, and contract set-aside eligibility. Her work ensures that small business concerns are integrated into the acquisition lifecycle from requirement development through award execution, aligning with federal mandates to maximize participation by disadvantaged and underserved vendors. She typically supports acquisitions related to administrative, operational, and policy support services essential to federal agency functions. While no specific contractor relationships are identified in available data, Callihan’s role centers on facilitating engagement with a broad spectrum of small business vendors, particularly those certified under socioeconomic programs. She works closely with contracting officers to identify qualified small businesses capable of delivering general government support services, fostering transparent and inclusive competition. Her approach emphasizes early vendor outreach, mentor-protégé initiatives, and pre-solicitation engagement to strengthen the small business pipeline. Callihan demonstrates a strong commitment to small business participation, with all known acquisitions classified as “No Set-Aside,” indicating a preference for open competition while still ensuring robust small business inclusion through other mechanisms such as subcontracting goals and small business set-aside eligibility determinations. Her focus remains on creating pathways for small businesses to compete fairly, even in unrestricted procurements, by ensuring requirements are structured to enable small firm responsiveness. Her primary procurement focus lies in NAICS 921190—Other General Government Support—which encompasses administrative services, policy analysis, program management support, and operational assistance for federal agencies. She specializes in acquisitions involving non-clinical, back-office functions critical to public sector efficiency, including data management, compliance reporting, and interagency coordination. Her technical expertise lies in understanding the nuanced requirements of government support services and translating them into solicitation language that promotes both competition and small business accessibility.
