Katharine K. Brennan

Katharine K. Brennan serves as Vice President at the PBS R00 Center for Broker Services within the General Services Administration’s Public Buildings Service, where she leads strategic real estate acquisition and leasing initiatives to secure commercial office space for federal agencies nationwide. In this capacity, she oversees the end-to-end procurement lifecycle for nonresidential property leases, ensuring alignment with federal workspace optimization goals, sustainability standards, and cost-efficiency mandates. Her portfolio primarily involves complex lease negotiations, space consolidation strategies, and long-term facility planning to support mission-critical federal operations across diverse geographic markets. Brennan maintains consistent contracting relationships with a select group of institutional 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 commercial landlords with proven experience in federal lease compliance, building modernization, and adaptive reuse of Class A and B office assets. Her procurement approach emphasizes stability, long-term tenancy, and performance-based lease terms that align with GSA’s asset management framework. Notably, Brennan’s contracting activity shows no reliance on socioeconomic set-asides, with 100% of awards issued under full and open competition. This reflects a strategic focus on market-driven value and operational scale rather than socioeconomic preferences, prioritizing the most qualified landlords capable of delivering mission-ready space under standardized federal lease terms. Her procurement expertise is concentrated exclusively in NAICS 531120—Lessors of Nonresidential Buildings—where she specializes in negotiating long-term leases for office, mixed-use, and government-leased facilities. She possesses deep technical knowledge of federal real estate standards, building code compliance, security requirements for federal tenants, and lease administration under the GSA Real Property Acquisition and Leasing Manual, making her a key leader in federal facility sourcing.
