Tammie Cassell

Tammie Cassell serves as the primary contracting lead for the Commanding General under the Department of the Navy, overseeing the acquisition of mission-critical maintenance, logistics, and specialized support services essential to naval and marine operational readiness. She manages a diverse portfolio of contracts focused on sustaining combat systems, mobility assets, and expeditionary infrastructure, ensuring equipment reliability across both garrison and deployed environments. Her work directly supports the agency’s strategic imperative to maintain high-readiness standards through timely, compliant, and technically sound procurement actions. Cassell maintains consistent working relationships with a core group of contractors including MANCON LLC, GEMINI TECH SERVICES LLC, CHEMBLE SOLUTIONS, LLC, MICROTECHNOLOGIES LLC, and SAELIG COMPANY, INC. These partnerships reflect a preference for established vendors with proven capabilities in technical support, maintenance logistics, and specialized equipment supply. Her contracting patterns emphasize performance-based service delivery, often leveraging indefinite-delivery/indefinite-quantity (IDIQ) and requirements contracts to ensure responsive, scalable support for dynamic operational needs. While the majority of her acquisitions—81.7%—are conducted without set-asides, Cassell demonstrates a meaningful commitment to small business participation, with 18.3% of awards structured as total small business set-asides under FAR 19.5. Her approach aligns with Department of the Navy goals to foster competition and enhance resilience through diverse vendor engagement, though she prioritizes capability and mission alignment over socioeconomic preferences when operational requirements demand it. Her procurement focus centers on NAICS categories including 337126 (furniture manufacturing), 336310 (motor vehicle engine parts), 517111 (wired telecommunications), 332311 (prefabricated metal structures), and 337910 (mattress manufacturing). These reflect an unconventional but mission-driven blend of support commodities and infrastructure components, indicating expertise in procuring niche, non-traditional items that enable sustainment and habitability in austere environments.
