Willie has also participated in numerous energy industry transactions for both private equity firms and strategic investors involving both regulated and unregulated targets.

Prior to that, Willie worked for The Walt Disney Company, where he supervised the federal and state and local tax compliance for the Cable and Broadcasting group and assisted in state income tax planning projects, corporate restructurings, exposure analysis, legislative analysis, and the state income tax provision.
