Arthur Mirante II is a principal and tri-state president of Avison Young, a Canadian commercial brokerage that made its first push into the New York City market last fall. An attorney by trade, Mirante joined the firm in April 2012 after 41 years at Cushman & Wakefield, where he became the firm’s first nonbroker CEO at age 40. In his 20 years as chief executive, he oversaw the firm’s expansion from 60 offices in the U.S. to 173 offices globally, and grew revenues tenfold, from $100 million to $1 billion. He stepped down as CEO in 2004 to become a broker and Cushman’s president of Global Development. He’s been involved in megadeals, including the record $1.8 billion acquisition of 666 Fifth Avenue in 2007 and the $1.72 billion sale of 200 Park Avenue in 2005.
