GSA Names Jennifer Hill and Mark Weiss to Lead Acquisition and Buildings Services

The General Services Administration (GSA) appointed Jennifer M. Hill commissioner of the Federal Acquisition Service (FAS) and Mark S. Weiss commissioner of the Public Buildings Service (PBS) on November 4, 2026. The leadership changes place new officials at the helm of two major GSA operating arms: one responsible for procurement and shared services across government, and the other for federal real estate operations. The appointments follow a period in which FAS had been led by an acting commissioner. They are management changes, not a solicitation, contract award, or announcement of a specific acquisition timetable.

Hill joined GSA in February 2026 as an adviser to Administrator Edward C. Forst and worked with FAS leadership on procurement consolidation, streamlined processes, and more strategic use of federal purchasing power. She brings 30 years of financial-services experience, including work at Goldman Sachs, Bank of America, and Citi. In her new role, she will oversee FAS operations, which provide procurement, technology, fleet, travel, and charge-card solutions to more than 80 federal agencies. GSA reports that FAS supports more than $125 billion in annual business volume involving approximately 16,000 companies—a scale that makes changes in its buying practices potentially consequential for contractors across multiple sectors.

Hill described her direction as: “I’m excited to execute on the Administrator’s vision for GSA acquisition: buy smarter, move faster, and reduce fraud.” For contractors, these priorities point to an emphasis on efficient buying, accountability, and the strategic use of government-wide purchasing power, but they do not establish specific new requirements. Companies selling through or pursuing acquisition channels should monitor future GSA guidance and solicitations rather than assume existing vehicles or terms will change. The supplied reporting identifies the ongoing OASIS+ rollout and possible changes involving the National Institutes of Health IT Acquisition and Assessment Center (NITAAC) and NASA SEWP VI as channels worth watching. GSA has also identified OneGov as a route for AI companies to engage with agencies.

Weiss joins GSA from Cushman & Wakefield, where he served as executive vice chairman, and brings 42 years of commercial real-estate experience. PBS oversees a federal portfolio of about 8,500 owned and leased assets totaling nearly 360 million square feet. Weiss said the service would “continue to advance the Trump-Vance Administration’s objectives and maintain the integrity of the federal government’s real estate portfolio.” His appointment is relevant to contractors in building operations, maintenance, construction, and related services because building utilization and property-disposition priorities can shape future requirements. However, GSA has not announced a specific PBS opportunity, procurement schedule, or change to existing work. Contractors should track agency planning and solicitations for concrete demand signals.
