Mary Catherine Williams

Mary Catherine Williams serves as a Senior Associate at the PBS R00 Center for Broker Services within the General Services Administration’s Public Buildings Service, where she plays a pivotal role in securing commercial real estate assets to support federal agency operations nationwide. Her responsibilities include managing the full lifecycle of lease acquisitions for nonresidential office space, from market analysis and solicitation development to contract award and performance monitoring. She operates within a mission-critical function that ensures federal agencies have secure, efficient, and cost-effective workspaces aligned with strategic footprint optimization goals. Her procurement activities are exclusively focused on leasing transactions under the 531120 NAICS code, emphasizing long-term, mission-aligned real estate solutions rather than construction or tenant improvement projects. Williams maintains consistent, high-volume relationships with a core group of commercial real estate owners and developers, including TWO CON LLC, ONNI TIMES SQUARE LP, CVD MAIN LLC, BELTSVILLE GSA FDA LLC, and CC OWNER LLC. These partnerships reflect a preference for established, institutional landlords with portfolios of Class A and B office properties in key metropolitan markets. Her contracting patterns indicate a reliance on experienced, large-scale property owners capable of delivering turnkey lease solutions with robust infrastructure and compliance frameworks, often involving complex space planning and federal security requirements. Williams’ procurement portfolio reflects no set-aside preferences, with 100% of her acquisitions awarded under full and open competition. This indicates a strategic focus on market-wide competition to achieve optimal value, rather than socioeconomic set-asides such as 8(a), HUBZone, or SDVOSB programs. Her approach prioritizes property quality, location, and operational efficiency over socioeconomic criteria. Her technical expertise is narrowly concentrated in NAICS 531120—Lessors of Nonresidential Buildings—where she specializes in procuring leased office space for federal tenants. She evaluates properties based on compliance with GSA standards for security, accessibility, energy efficiency, and ADA compliance, demonstrating deep familiarity with federal real estate leasing regulations and facility management requirements.
