Mosler tells GlobeSt.com Hollander's presence is representative of an ongoing effort to "continue building the future superstar talent and Cushman and Wakefield. David is moving up and, like some of our other talent, will be the future of this company down the road."

Hollander, an eight-year Insignia vet, says he will continue to work both the tenant rep and agency side of the business. He tells GlobeSt.com his reputation at I/ESG was that of a "rising young star" and says he "will be using C&W's platform to build on that."

The former I/ESG managing director worked on Mary Ann Tighe's team before Tighe bolted the firm for CBRE. In one of his last Insignia deals, Hollander completed a 100,000-sf lease at 230 Park for Swiss Re. He also worked with Tighe on a 400,000-sf deal at 825 Third Ave.
