  • After purchasing a medical portfolio consisting of 22 buildings and totaling over 1.5 million square feet located throughout the Washington DC Metropolitan Area, we needed a brokerage firm that could competently represent our interests and who also had the expertise in the local healthcare market. After interviewing three national brokerage companies and two local firms, we split the portfolio representation with Gittleson Zuppas Medical Realty and one national firm. GZ quickly proved to be a highly qualified provider of leasing services and brokerage, which perpetuated GZ being awarded the remaining portion of our medical office portfolio. Gittleson Zuppas is an essential partner to our business strategy and upholds the highest level of service and expertise in the DC medical office market.- Brian Mutchler - Senior Managing Director, Harrison Street Real Estate Capital
  • I have had the pleasure of working with Gittleson Zuppas commercial real estate brokerage for nearly ten years. They were principally responsible for leasing our 80,000 sq. ft. Class A medical office building. They accomplished this in record time, providing great advice, and working out win-win scenarios with the landlord and tenants. The entire process was made very pleasurable as a result of their professionalism. David Gittleson, Nick Zuppas, and Peter Papantoniou are hardworking, honest professionals that have an excellent grasp of the medical real estate market in the metropolitan area. They are extremely responsive to requests for market information.
