As chief executive officer of Global Crossing Limited since October 2001, John steered the company from its entrepreneurial roots to its current operational focus with the completion of the world's first integrated global IP-based network. He kept Global Crossing's network, customer base and employees intact through 681 days of restructuring, emerging on December 9, 2003 with a streamlined cost structure, improved customer satisfaction scores and near-perfect network operations. The company has now grown into a leading provider of IP services worldwide, with 5,000 employees and a network delivering services to 690 cities around the world.

At AT&T, where John began his telecommunications career, he rose rapidly through the ranks to become one of the telecom giant's youngest officers. He served as head of global strategy and business development and led the company's expansion in Asia as president and chief executive officer of AT&T Asia/Pacific from April 1994 to November 1997. From 1997 to 1998 he was president of worldwide outsourcing at AT&T Solutions, the unit that provided customized support to the company's largest customers.

From AT&T John moved to Dell Computer Corporation, spearheading its expansion in Asia so successfully as president of Asia-Pacific from 1998 until February 2000 that he was also named president of Dell's operations in Europe, the Middle East and Africa. He then took on the challenge of president and chief executive officer of Asia Global Crossing from February 2000 until January 2002, building a new company from scratch, conducting its successful initial public offering and overseeing construction of its leading-edge fiber-optic network before being appointed to the top spot at Global Crossing.

A Massachusetts native, John received a bachelor's degree in business administration from the University of Massachusetts; a Master of Business Administration degree from Fairleigh Dickinson University, where he is currently a member of FDU’s Global Advisory Board; and a master's degree in science as an Alfred P. Sloan Fellow at the Massachusetts Institute of Technology. He also attended the Harvard Business School Management Development Program in 1989.

John was a nationally competitive runner in college and post college, and still competes -- and wins -- in Corporate Challenge events with fellow employees around the world to promote community and team spirit. For the last five years he has completed the Boston Marathon with his brother as a member of the Dana-Farber Marathon Challenge team, raising approximately $670,000 for the charity to help fight cancer. John is also a former board member of the USA Track & Field Foundation.
