Greenberg Traurig corporate shareholder Kara MacCullough led a team of U.S. attorneys in closing a $3.65 billion financing deal for a Boca Raton company that provides infrastructure for wireless communications.

MacCullough, who works mostly in Fort Lauderdale plus the firm’s Washington office, represented SBA Communications Corp., a publicly traded company that builds, manages and owns wireless communications infrastructure such as cell towers. The financing also was for SBA’s wholly owned subsidiary SBA Senior Finance II LLC.
