Diemle T. Phan serves as a Contract Specialist within the General Services Administration’s Federal Acquisition Service, Region 9, where they play a pivotal role in executing mission-critical procurements that support federal operational efficiency and digital modernization. Specializing in professional, scientific, and technical services, Phan manages the full lifecycle of acquisitions—from market research and solicitation development to award and contract administration—ensuring compliance with FAR regulations and GSA’s strategic priorities. Their portfolio primarily encompasses IT modernization, systems integration, and logistics consulting contracts that sustain federal workforce productivity and infrastructure resilience across the region. Phan cultivates collaborative relationships with a diverse range of vendors, including established systems integrators, niche IT service providers, and specialized consulting firms. While no single contractor dominates their portfolio, their procurement patterns reflect consistent engagement with firms capable of delivering custom software development, enterprise IT support, and technical advisory services. Their approach emphasizes performance-based contracting and clear statement of work development to ensure accountability and mission alignment. With a strong preference for open competition—71.4% of acquisitions are non-set-aside—Phan also demonstrates meaningful support for small business participation, allocating 28.6% of awards to Total Small Business Set-Asides under FAR 19.5. This reflects a balanced commitment to both competition and socioeconomic goals, fostering opportunities for small businesses without compromising acquisition efficiency or mission readiness. Their technical focus centers on NAICS 541511 (Custom Computer Programming Services), with significant activity in computer equipment wholesale (423430) and management consulting (541611, 541614). Phan regularly procures software development, systems engineering, and logistics optimization services, demonstrating deep expertise in IT modernization, digital infrastructure, and operational process improvement for federal clients.
