Margretta Milles

Margretta Milles serves as a key procurement professional within the Public Buildings Service’s PBS R00 Center for Broker Services, responsible for managing the acquisition of commercial real estate assets to support federal agency operations nationwide. She specializes in leasing nonresidential office space and managing long-term property agreements under the General Services Administration’s real estate portfolio. Her work directly enables federal agencies to secure secure, efficient, and cost-effective workspace by negotiating leases, conducting market analyses, and ensuring compliance with federal property management standards. Milles handles complex real property transactions, including ground leases, build-to-suit arrangements, and space expansion options, all aligned with the agency’s mission to optimize the federal footprint. She maintains consistent contracting relationships with a select group of commercial real estate developers and property owners, 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 commercial landlords with experience in federal compliance, building modernization, and lease administration. Milles works closely with these entities to structure leases that meet GSA’s operational requirements, sustainability goals, and security protocols, often engaging in multi-year negotiations and lease renewals. Milles’ procurement activity is entirely non-set-aside, with 100% of contracts awarded under full and open competition. This reflects a strategic focus on market-driven outcomes and broad vendor participation rather than socioeconomic set-asides, prioritizing competitive pricing and property suitability over socioeconomic classifications. Her primary procurement focus is on NAICS 531120—Lessors of Nonresidential Buildings—where she specializes in leasing commercial office space, including Class A and B properties in urban and suburban markets. Her expertise lies in evaluating building conditions, lease terms, and facility compatibility with federal security and accessibility standards, making her a specialist in federal real estate leasing and asset management.
