Spillane joined Cushman & Wakefield in 1989, when the real estate firm was known only in the U.S., and helped establish the company as a global brand that now operates 221 offices in 58 countries.
"For two decades, Terry was the face of Cushman & Wakefield to the world, managing strategic media relationships across America and internationally," Bruce Mosler, chief executive officer of Cushman & Wakefield, wrote in a letter to employees.
"As the firm grew, he continued to serve as international liaison for corporate communications in New York. He contributed immensely to the firm's reputation as a market and thought leader. More important than any story idea was the integrity and trustworthiness Terry communicated every day.
"Though known affectionately as 'Bulldog' for his persistence and professional success, those who had the chance to work with him loved him for his personal warmth, sense of fair play and gentleness of spirit....Terry loved Cushman & Wakefield — almost as much as he loved New York and the Yankees."
Before joining Cushman & Wakefield, Spillane was a senior account executive in the media relations department at Metropolitan Life Insurance Co. Before that, he was assistant commissioner of the Metro Atlantic Athletic Conference, one of the Division 1 conferences that make up the National Collegiate Athletic Association, where he helped get the league off the ground in its infancy. Earlier, he was assistant publicity director at Yonkers Raceway and a sports reporter for the New York Post.
Spillane was a member of the alumni board of Iona College in New Rochelle, N.Y.
He is survived by his wife, Mary Ann, and their two daughters, Carolyn and Kate. A funeral mass was held Monday.
