David Kosiorek

David Kosiorek serves as a Contracting Officer within the GSA/FSS Office of Supply Center – Office Equipment, where he plays a pivotal role in enabling federal workforce productivity through the acquisition of mission-critical office supplies, printed materials, and specialized equipment. Responsible for managing full lifecycle procurements under the Federal Supply Schedule and other simplified acquisition authorities, Kosiorek ensures compliance with FAR regulations while delivering cost-effective, reliable solutions to federal agencies nationwide. His portfolio spans a broad range of administrative support products and services, with a strong emphasis on streamlining procurement processes to meet the operational needs of the federal government. Kosiorek maintains collaborative relationships with a diverse base of vendors, including merchant wholesalers, custom software developers, and small-batch manufacturers. He routinely engages with firms holding GSA Schedule contracts and works closely with suppliers who meet stringent quality, delivery, and service standards. His contracting approach prioritizes vendor reliability, supply chain resilience, and adherence to federal acquisition policies, fostering long-term partnerships that support consistent service delivery across the government. Kosiorek demonstrates a robust commitment to small business participation, with approximately 40% of his acquisitions set aside for total small businesses under FAR 19.5, and an additional 4% reserved specifically for service-disabled veteran-owned small businesses. While the majority of his awards remain open to all competitors, his consistent use of socioeconomic set-asides reflects a deliberate strategy to expand opportunities for small, disadvantaged, and veteran-owned firms within the federal supply base. His primary procurement focus lies in NAICS 541511 (custom computer programming), 424120 (stationery and office supplies wholesale), 322211 (corrugated box manufacturing), and 423430 (computer equipment wholesale). This specialization enables him to efficiently source everything from branded office stationery and printed forms to bespoke software solutions and packaging materials, combining technical understanding with sound contracting judgment to meet the evolving administrative needs of federal agencies.
