Mark McDermott

Mark McDermott serves as Senior Vice President at the PBS R00 Center for Broker Services within the General Services Administration’s Public Buildings Service, where he leads strategic real estate acquisition and leasing initiatives to secure optimal nonresidential workspace for federal agencies nationwide. In this capacity, he oversees the end-to-end procurement lifecycle for commercial office space and related facility services, ensuring compliance with federal property management standards and alignment with agency footprint optimization goals. His portfolio is exclusively focused on real property leasing transactions, with an emphasis on long-term, mission-critical space solutions that support operational efficiency and cost containment across the federal landscape. McDermott maintains enduring 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 are characterized by recurring, high-volume leasing engagements, often involving multi-tenant office buildings and institutional-grade properties in high-demand urban and suburban markets. His procurement approach prioritizes stability, scale, and performance-based lease terms, fostering long-term vendor collaboration grounded in transparency and predictable contract execution. There is no set-aside preference in McDermott’s procurement portfolio; all acquisitions are conducted under full and open competition. This reflects a deliberate strategy to maximize market competitiveness and leverage the broadest possible pool of qualified real estate providers, with no socioeconomic set-asides applied to any awarded contracts. His procurement activity is entirely concentrated under NAICS 531120—Lessors of Nonresidential Buildings (except Miniwarehouses)—demonstrating deep specialization in commercial real estate leasing. He exclusively procures leased office space and related property services, with expertise in evaluating building condition, location suitability, lease structure, and federal compliance requirements under the Federal Property and Administrative Services Act.
