General Motors has appointed Craig Glidden as general counsel, effective March 1. Glidden will lead a team of staff attorneys who are integrated into all of GM’s regional and functional teams in more than 30 countries.

Before joining GM, Glidden was executive vice president and chief legal officer for LyondellBasell Industries, one of the world’s largest plastics, chemicals and refining companies. He oversaw the company’s global legal, communications, government affairs and compliance groups.

Prior to joining LyondellBasell in August 2009, Glidden served as senior vice president, general counsel and corporate secretary of Chevron Phillips Chemical. Prior to joining Chevron Phillips Chemical, he was in private law practice.
