She fosters collaborative relationships with both large-capacity providers and small businesses, emphasizing transparency, performance-based outcomes, and contract compliance throughout the award and administration phases. Greeley’s procurement portfolio reflects a strong preference for open competition, with approximately 77.8% of awards issued without set-asides. However, she consistently supports small business participation, with 22.2% of contracts awarded under Total Small Business Set-Asides in accordance with FAR 19.5. Her approach aligns with agency goals to broaden vendor diversity while maintaining rigorous performance standards, ensuring small businesses have equitable access to high-impact procurement opportunities.
