Cassidy Turley was a privately held commercial real estate brokerage and services company based in Washington, D.C., that at the time of its merger in late 2014 into DTZ, had more than 3,700 employees working in commercial real estate. Though not one of the biggest brokerages in New York, the local office of Cassidy Turley maintained a sizable presence in the city, particularly through its office leasing team. With the merger, the Cassidy Turley name was retired and the New York office merged with the smaller New York office of DTZ in early 2015. Cassidy Turleys clients in New York included Coty, Random House, LVMH, City Harvest and Guggenheim Partners. The addresses where the firm has worked major deals include the commercial condo at 40 Broad Street; the Empire State Building; 399 Park Avenue; and 150 East 42nd Street. The firm also produces reams of data, including a quarterly Manhattan office market report. Cassidy Turley was created in 2008 out of the merger of four different firms nationwide, including Colliers ABR in New York. Its New York region president was Peter Hennessy and its New York region managing principal was Joseph Swingle at the time of the merger into DTZ. The New York office of Cassidy Turley was originally Abrams Benisch Riker, formed in 1978 by former members of Cross & Brown Company.
