Haddadin was former condo board president for CBRE’s brokered sale at 2625 N. Clark St. in Chicago. That building underwent the largest condo deconversions in the city to date. “During the process of selling 2625 N. Clark, Sam was very resourceful and helpful,” said John Jaeger, executive vice president with CBRE, in prepared remarks. “Condo deconversions are very complex undertakings and he showed a strong aptitude for navigating the process. This experience and his financial background will be a major benefit to our clients as we continue to expand this practice and execute these transactions.”
