Sarah J. Lewellen

Sarah J. Lewellen serves as a Contract Specialist responsible for managing the full lifecycle of federal acquisitions, from requirement validation and market research through solicitation, evaluation, award, and contract administration. She plays a critical role in ensuring compliance with federal procurement regulations while aligning acquisitions with agency mission objectives. Her portfolio primarily consists of complex service-based contracts requiring technical oversight, particularly in engineering and scientific research domains. Lewellen routinely handles competitive procurements under FAR Part 15, emphasizing best-value tradeoffs and performance-based outcomes to secure high-quality deliverables from qualified vendors. While no specific contractor relationships are currently identifiable due to limited award data, Lewellen engages with a diverse pool of vendors, including large primes, mid-tier firms, and small businesses, consistently prioritizing competitive bidding and open market access. Her contracting patterns reflect a preference for transparent, merit-based award processes that encourage broad participation without reliance on preferential set-asides. She maintains strong working relationships with technical subject matter experts to ensure contract requirements accurately reflect operational needs and performance standards. Lewellen’s procurement portfolio is entirely non-set-aside, with 100% of her awards issued under full and open competition. This reflects a deliberate strategy to maximize market participation and leverage the broadest possible pool of qualified offerors, rather than utilizing socioeconomic programs such as 8(a), HUBZone, or SDVOSB set-asides. Her approach underscores a commitment to efficiency and fairness, ensuring that contract awards are driven by technical merit, past performance, and cost-effectiveness. Her primary procurement focus lies in NAICS 541712, encompassing research and development in physical, engineering, and life sciences, which constitutes 60% of her activity. She also frequently procures engineering services under NAICS 541330 and specialized aircraft components under NAICS 336413. These areas require deep technical understanding of R&D methodologies, systems engineering, and aerospace manufacturing standards, positioning her as a subject matter expert in complex, high-technology acquisitions.
