Stephen A. Deffenbaugh

Stephen A. Deffenbaugh serves as a Contract Specialist responsible for managing the full lifecycle of federal acquisitions, from requirement validation through contract award and administration. He plays a critical role in ensuring compliance with the Federal Acquisition Regulation (FAR) while advancing mission-critical procurement objectives. His portfolio primarily encompasses services and supplies related to outpatient mental health and substance abuse treatment, food manufacturing, and dairy distribution, reflecting a diverse yet specialized acquisition focus. Deffenbaugh works closely with program stakeholders to translate operational needs into solicitation requirements, ensuring competitive, transparent, and legally sound contracting outcomes. While specific contractor names are not available, Deffenbaugh maintains a consistent engagement pattern with vendors across the healthcare services and food supply sectors. He cultivates relationships with both large-capability firms and small businesses capable of delivering specialized services, including clinical support, food production, and wholesale distribution. His approach emphasizes performance-based contracting and clear statement of work development to ensure accountability and service quality across awarded contracts. Deffenbaugh demonstrates a strong commitment to small business participation, with nearly 29% of his acquisitions structured as Total Small Business Set-Asides under FAR 19.5. He consistently prioritizes socioeconomic programs that expand market access for small businesses, aligning with federal goals to increase contracting opportunities for disadvantaged and underserved entrepreneurs. His pattern reflects a deliberate effort to foster competition and diversity in the vendor base without relying on other set-aside categories such as 8(a), HUBZone, or SDVOSB. His primary procurement focus centers on NAICS 621420 (Outpatient Mental Health and Substance Abuse Centers), followed by food manufacturing and distribution categories including 311999, 311511, and 311812. This specialization indicates deep expertise in procuring behavioral health services and perishable food commodities, requiring nuanced understanding of regulatory standards, supply chain logistics, and quality control protocols. Deffenbaugh’s technical domain knowledge ensures that acquisitions meet both operational needs and public health standards.
