Sierra Miller

Sierra Miller serves as a key procurement lead within the W7NR Uspfo Activity Nyang 174, a Department of the Army installation support unit responsible for sustaining mission-critical infrastructure and operational systems. In this role, she manages the full lifecycle of acquisitions for facility modernization, utility upgrades, and physical security enhancements, ensuring compliance with DoD standards and federal contracting regulations. Her portfolio primarily encompasses technical installations and communications systems essential to base resilience, aligning directly with the agency’s strategic imperative to maintain mission-ready facilities across its operational footprint. Miller’s contracting approach is defined by a robust emphasis on small business participation, with 100% of her acquisitions structured as total small business set-asides under FAR 19.5. She consistently prioritizes partnerships with small businesses, including those certified under 8(a), HUBZone, and SDVOSB programs, fostering a contracting environment that promotes economic inclusion and innovation from underserved vendor communities. Her procurement patterns reflect a deliberate strategy to build long-term vendor capacity and ensure competitive, agile supply chains aligned with national defense readiness goals. Her primary procurement focus lies in NAICS 334290 (Other Communications Equipment Manufacturing), where she acquires specialized military-grade communication hardware and network-enabling systems, and NAICS 238220 (Plumbing, Heating, and Air-Conditioning Contractors), where she oversees integrated utility and environmental control system installations. These domains require deep technical expertise in secure communications architecture and facility infrastructure modernization, positioning Miller as a specialist in mission-critical, low-visibility systems that underpin operational continuity. She works closely with a network of qualified small business contractors who demonstrate proven capability in defense-compliant manufacturing and installation services.
