Jamarr Zellner

Jamarr Zellner serves as a Transaction Manager at the Pbs R00 Center for Broker Services within the General Services Administration’s Public Buildings Service, where he plays a pivotal role in executing real estate acquisition strategies to support federal workspace requirements. He manages the full lifecycle of commercial lease transactions for nonresidential properties, ensuring alignment with federal efficiency goals and cost-effective footprint optimization. His work directly supports the agency’s mission to secure secure, functional, and strategically located office spaces across the United States, primarily through long-term lease agreements with private property owners and real estate entities. Zellner 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 are centered on the acquisition of leased commercial office space, with a focus on turnkey, fully operational facilities that meet federal security and operational standards. His approach emphasizes streamlined negotiations, compliance with GSA leasing protocols, and reliable vendor performance to ensure seamless occupancy and service delivery. Zellner’s procurement portfolio reflects a strict preference for no set-aside classifications, with 100% of his transactions awarded under full and open competition. This reflects a strategic alignment with the agency’s priority to maximize value and flexibility in securing high-demand urban and suburban real estate assets, rather than targeting socioeconomic categories. His contracting patterns indicate a focus on efficiency and scale over socioeconomic preferences. His primary technical domain is NAICS 531120—Lessors of Nonresidential Buildings (except Miniwarehouses)—where he specializes in procuring turnkey leased office environments, including build-to-suit and re-tenanting arrangements. He possesses deep expertise in commercial real estate leasing structures, space planning compliance, and federal facility standards, ensuring all properties meet GSA’s stringent operational and accessibility requirements.
