Hartz Mountain Industries, Inc. has promoted Constantino "Gus" Milano as a managing director. In his new role, he will assume additional responsibility for the company's commercial real estate portfolio, which has expanded from its emphasis on office parks, industrial property, shopping centers and hotels to include an investment in residential properties. Milano has been integral to the company's success since joining Hartz Mountain Industries, Inc. in 1981. Starting as an analyst on the first generation of Harmon Cove developments, Gus worked through the ranks of the finance department before becoming its senior executive and then assuming responsibility for leasing. Hartz's 2011 leasing performance was the company's best since 2005. "Gus has guided the company in some tough economic times," said Emanuel Stern, president and COO of Hartz Mountain Industries. "He is a consummate leader whose unique insight has created value for this company, and he has played an integral role in transforming the company into what it is today."
