Mary Thomsen

Mary Thomsen serves as a key procurement professional within the Public Buildings Service’s R10 Services Acquisitions Branch, where she manages the acquisition of integrated facilities support services essential to sustaining federal building operations. Her responsibilities encompass the full lifecycle of contract execution—from requirements definition and market research to award and performance monitoring—for mission-critical services that ensure the safety, accessibility, and operational resilience of federal infrastructure. She specializes in procuring comprehensive facilities management solutions, including maintenance, janitorial, security, and building systems support, aligning acquisitions with GSA’s mandate to deliver efficient, compliant, and sustainable public environments. Thomsen collaborates with a diverse pool of contractors specializing in facilities operations and building equipment installation, fostering long-term partnerships with firms capable of delivering scalable, performance-based services across multiple federal sites. While no single contractor dominates her portfolio, she consistently engages vendors with proven expertise in integrated facilities management, preventive maintenance systems, and ADA-compliant infrastructure upgrades. Her contracting approach emphasizes accountability, performance metrics, and vendor reliability, ensuring service continuity and regulatory adherence. Thomsen’s procurement activities reflect a strong preference for full and open competition, with 100% of her acquisitions issued without set-aside designations. This indicates a strategic focus on maximizing market competition and leveraging broad industry capability rather than socioeconomic set-asides, though she remains compliant with all federal small business participation requirements. Her primary procurement focus lies in NAICS 561210 (Facilities Support Services), encompassing custodial, groundskeeping, and building operations, complemented by NAICS 238290 (Other Building Equipment Contractors) for specialized mechanical, electrical, and life safety system installations. She possesses deep technical expertise in federal facility standards, including GSA’s Sustainability and Resilience Guidelines, and routinely procures services that support energy efficiency, accessibility compliance, and infrastructure modernization initiatives.
