According to CB Richard Ellis, Ellen Rudin, a 20 year veteran of the commercial real estate industry, has been appointed managing director with responsibility for the firm's market-leading Long Island operations. In this capacity, Rudin will oversee day-to-day operations of the firm's Woodbury and Long Island City offices. She succeeds Brian Dugan, who will remain with CBRE in a senior brokerage and business development role. Prior to this appointment, Rudin served as senior counsel with the CBRE Tri-State Legal team. Her intimate knowledge of the industry and extensive experience negotiating complex transactions have helped guide many of the firm's top professionals through complicated, high-profile transactions. "Ellen's extensive leadership capabilities make her an excellent choice to direct further growth of our Long Island operations, an essential element of CBRE's powerful platform for client service," said Mitchell Rudin, president of CBRE's New York Tri-State Region. Rudin will oversee its brokerage activity, as well as overall management for the region, which consists of 45 real estate professionals and support staff, including corporate services; office, industrial and retail leasing; investment sales; asset management; and research, marketing and administrative support.
