Sheree A. Johnson

Sheree A. Johnson serves as a Purchasing Agent for the Animal and Plant Health Inspection Service (APHIS) under the U.S. Department of Agriculture, where she manages the acquisition of critical scientific, technical, and operational resources essential to national biosecurity. Her role centers on executing competitive procurements that support APHIS’s mission to detect, contain, and prevent the spread of invasive pests and animal diseases. She routinely handles acquisitions for laboratory instrumentation, diagnostic reagents, aviation maintenance services, and specialized fabrication equipment, ensuring alignment with federal procurement regulations and agency-specific biosecurity protocols. Johnson maintains consistent working relationships with a select group of specialized vendors, including Aerospace & Commercial Technologies, LLC, Thorobred Aviation Maintenance, Inc., and Trace First Limited, reflecting a focus on niche providers capable of supporting high-integrity scientific and aviation operations. Her contracting patterns emphasize technical precision and regulatory compliance, often requiring vendors to demonstrate expertise in biosafety-compliant manufacturing, field-deployable diagnostics, or FAA-certified aviation maintenance. These partnerships are characterized by repeat engagement and a preference for firms with proven capabilities in mission-critical domains. A strong advocate for small business participation, Johnson consistently prioritizes Small Business Set-Asides under FAR 19.5, with nearly 70% of her awards designated for small businesses. This reflects a deliberate strategy to expand vendor diversity and strengthen the ecosystem of specialized suppliers capable of supporting APHIS’s scientific and operational needs. Her procurement approach actively leverages socioeconomic programs to foster innovation and resilience within the supply chain. Her primary procurement focus lies in NAICS 334516 (analytical laboratory instruments), 325413 (in-vitro diagnostic substances), and 334510 (electromedical apparatus), indicating deep engagement with diagnostic, biosurveillance, and laboratory automation technologies. She also procures specialized chemical preparations and fabricated metal components used in containment systems and field equipment, demonstrating technical fluency in life sciences and biosecurity infrastructure procurement.
