Diona Sims

Diona Sims serves as a Contract Specialist responsible for managing the full lifecycle of procurement actions, from requirement validation and market research to contract award and administration. Her role is central to ensuring compliance with federal acquisition regulations and advancing the agency’s mission through transparent, efficient, and equitable contracting practices. She primarily handles competitive solicitations for apparel and textile services, applying sound judgment in evaluating technical proposals, assessing contractor performance, and mitigating acquisition risks. Her work ensures that procurement activities align with statutory mandates and agency objectives, fostering accountability and value in every contract action. Diona collaborates with a diverse base of vendors specializing in cut-and-sew apparel manufacturing, including small businesses with expertise in uniform production, protective workwear, and custom textile solutions. While no single contractor dominates her portfolio, she consistently engages with firms that demonstrate strong operational capacity, quality control, and compliance with labor and sourcing standards. Her working relationships are built on clear communication, timely feedback, and a commitment to fair competition, encouraging both established and emerging suppliers to participate in federal contracting opportunities. Diona demonstrates an unwavering commitment to small business participation, with 100% of her acquisitions structured as total small business set-asides under FAR 19.5. This reflects a deliberate strategy to maximize economic opportunity for small, independently owned enterprises and ensure broad-based access to federal procurement. Her contracting patterns prioritize socioeconomic goals, consistently channeling awards to small businesses without further subclassifications, thereby supporting the foundational role of small firms in the federal supply chain. Her primary procurement focus is on NAICS 315210, Cut and Sew Apparel Contractors, encompassing the design, manufacturing, and delivery of tailored garments including uniforms, protective clothing, and specialized apparel. She possesses deep technical familiarity with textile specifications, production timelines, quality assurance protocols, and compliance with federal performance standards for wearables used in operational environments. This specialization enables her to effectively evaluate technical capabilities and ensure deliverables meet mission-critical requirements.
