Aaron M. Posthumus

Aaron M. Posthumus serves as a Contract Specialist at the Federal Correctional Institution Berlin under the Bureau of Prisons, where he manages the acquisition of mission-critical food services and related support contracts to ensure the safe, humane, and nutritionally compliant sustenance of the incarcerated population. His procurement activities center on securing perishable, culturally appropriate, and medically tailored food products that meet federal dietary standards, including religious and therapeutic requirements. He handles a wide range of acquisitions under FAR Part 13 and Part 14, including blanket purchase agreements, indefinite-delivery/indefinite-quantity contracts, and micro-purchases, ensuring strict compliance with USDA and HACCP guidelines. Posthumus collaborates with a diverse network of vendors, including specialty food manufacturers, perishable food distributors, and merchant wholesalers, to maintain a resilient and responsive supply chain. He cultivates long-term partnerships with firms capable of delivering just-in-time, temperature-controlled logistics and adhering to stringent federal food safety protocols. His working relationships emphasize reliability, scalability, and adherence to federal procurement integrity standards, with frequent engagement with vendors holding food handling certifications and USDA inspection compliance. A strong advocate for small business participation, Posthumus consistently prioritizes small business set-asides, with approximately 80% of his acquisitions designated as Total Small Business Set-Asides under FAR 19.5. He actively seeks out 8(a), HUBZone, and SDVOSB-certified firms, integrating socioeconomic goals into every solicitation to expand economic opportunity while ensuring mission readiness. His contracting patterns reflect a deliberate strategy to build capacity among small, disadvantaged suppliers in the food services sector. His primary procurement focus lies in NAICS 311999 (Miscellaneous Food Manufacturing) and 311991 (Perishable Prepared Food Manufacturing), supplemented by significant activity in 424410 and 424430 for grocery and dairy distribution. He possesses deep technical expertise in perishable supply chain management, dietary compliance, and cold chain logistics, ensuring that all acquisitions align with the Bureau of Prisons’ mandate for safe, equitable, and nutritionally sound food service delivery.
