DTZ is one of the world’s leading real estate advisors, rooted in a long history in real estate markets dating back from 1784.

Since the merger, DTZ Winssinger has grown its local network with the opening of DTZ Antwerp in 1996, DTZ Luxembourg in 1998 and DTZ Liege in 2002. DTZ has doubled in size every five years since 1983. Mr. Winssinger’s brother, Philippe Winssinger, is the director of DTZ Winssinger.
