Mareen M. Stevens

Mareen M. Stevens serves as a Contracting Officer within the PBS R6 Services Acquisition Branch of the General Services Administration’s Public Buildings Service, where she plays a pivotal role in securing essential facilities support services to maintain the operational integrity of federal buildings. Her responsibilities encompass the full lifecycle of procurement—from market research and solicitation development to contract award and administration—focusing primarily on custodial, building operations, and food service contracts. She ensures compliance with federal acquisition regulations while aligning acquisitions with the agency’s mission to provide safe, clean, and efficiently managed federal workspaces. Stevens cultivates collaborative relationships with a diverse pool of vendors, including large service providers and small business contractors specializing in building maintenance and operations. Her contracting approach emphasizes performance-based outcomes and service-level accountability, fostering long-term partnerships grounded in quality, reliability, and regulatory compliance. While no single contractor dominates her portfolio, she consistently engages firms with proven expertise in federal facility support, ensuring continuity of service across multiple sites. Her procurement strategy reflects a strong commitment to small business participation, with approximately one-third of her awards structured as total small business set-asides under FAR 19.5. She actively prioritizes socioeconomic programs that expand opportunities for small businesses, though the majority of her contracts remain open to all competitors, balancing equitable access with mission needs. Stevens specializes in NAICS codes 722310 (Food Service Contractors), 561790 (Other Services to Buildings and Dwellings), and 561720 (Janitorial Services), reflecting her deep expertise in custodial, grounds maintenance, and facility support services. She procures comprehensive cleaning, waste management, landscaping, and on-site food service solutions, demonstrating technical fluency in performance standards, facility-specific requirements, and federal sustainability mandates. Her work ensures that federal facilities remain functional, compliant, and conducive to productive government operations.
