Isaac A. Don Willies

Isaac A. Don Willies serves as a Contract Specialist at Naval Medical Center San Diego (N00259), where he plays a pivotal role in executing procurement actions critical to sustaining operational medical readiness for the Department of the Navy. He manages a diverse portfolio of acquisitions focused on electromedical equipment, surgical supplies, and diagnostic laboratory systems, ensuring compliance with FAR and DOD acquisition regulations. His work directly supports the center’s mission to deliver advanced clinical care and maintain combat-ready medical forces through timely and compliant contracting for mission-critical technologies. Willies engages with a broad spectrum of vendors, including manufacturers of surgical instruments, in-vitro diagnostic substances, and analytical laboratory equipment, fostering partnerships with both large-scale defense contractors and specialized medical technology firms. His contracting approach emphasizes technical evaluation, performance-based requirements, and lifecycle cost considerations to ensure equipment reliability and interoperability within naval medical environments. He maintains consistent collaboration with suppliers who demonstrate quality assurance, regulatory compliance, and responsiveness to urgent operational needs. While the majority of his acquisitions are conducted under open competition—reflecting an 89.5% non-set-aside pattern—Willies actively supports small business participation through Total Small Business Set-Asides under FAR 19.5, demonstrating a deliberate commitment to socioeconomic contracting goals. He routinely awards contracts to small businesses capable of delivering specialized medical technologies, aligning with DOD’s broader objectives to expand supplier diversity and enhance innovation through the small business base. His primary procurement focus centers on NAICS 811219 (Medical and Diagnostic Laboratory Services), 339113 (Surgical Appliance and Supplies Manufacturing), and 325413 (In-Vitro Diagnostic Substance Manufacturing), reflecting deep expertise in biomedical instrumentation, surgical tooling, and diagnostic reagent procurement. Willies brings specialized knowledge in the technical specifications and regulatory standards governing medical device acquisition, ensuring all procurements meet FDA, ANSI, and military performance benchmarks.
