Diane L. Stetser

Diane L. Stetser serves as a Contracting Officer within the PBS R3 Acquisition Management Division of the General Services Administration’s Public Buildings Service, where she plays a pivotal role in executing strategic procurements to secure federal facility services and real estate assets across Region 3. Her responsibilities encompass the full lifecycle management of contracts for architectural design, facility maintenance, administrative support, and management consulting services critical to modernizing and sustaining federal workspaces. She ensures compliance with federal acquisition regulations while aligning procurements with the agency’s mission to deliver safe, efficient, and mission-critical infrastructure solutions. Stetser cultivates collaborative relationships with a diverse pool of vendors specializing in professional services, particularly in facility management and administrative support. While no single contractor dominates her portfolio, she regularly engages with firms offering integrated facility services, architectural design, and operational consulting, fostering partnerships that emphasize performance-based outcomes and contract compliance. Her working relationships reflect a balanced approach between established service providers and agile small business contractors, prioritizing reliability and regulatory adherence. Her procurement patterns show a strong preference for open competition, with 83.3% of her acquisitions conducted without set-asides, reflecting a focus on broad market competition. However, she consistently reserves 16.7% of opportunities for Total Small Business Set-Asides under FAR 19.5, demonstrating a deliberate commitment to expanding small business participation without favoring specific socioeconomic categories such as 8(a), HUBZone, or SDVOSB. Stetser’s primary NAICS focus areas include 541611 (Administrative Management Consulting), 561499 (Other Business Support Services), 541310 (Architectural Services), and 561110 (Office Administrative Services). She specializes in procuring professional services that enhance facility operations, streamline federal workspace management, and support long-term infrastructure modernization, positioning her as a key practitioner in the intersection of real estate acquisition and professional services contracting.
