Delek US Holdings has hired a veteran of Gulf Oil and PBF Energy to be its chief commercial officer and help refine its strategies.

Todd O’Malley comes to Brentwood-based Delek and its majority-owned Delek Logistics Partners after nearly a year of leading energy consulting and investment firm Citizens Companies and three years of leading TKO Energy Enterprises, his own advisory services firm. Before that, the 47-year-old was chief commercial officer at Gulf Oil for nearly two years and held various roles at PBF Energy, including as president of its PBF Logistics general partnership.
