On September 28, 2026, Par Pacific Holdings, Inc. announced a leadership transition within its refining and logistics division. The company appointed Jerry Stumbo as Executive Vice President of Refining and Logistics, effective immediately. Stumbo succeeds Richard Creamer, who will retire from the company on or about April 1, 2027. Until his retirement, Creamer will serve as Senior Advisor to the company.
Stumbo joins Par Pacific from Valero Energy, where he most recently served as Vice President and General Manager of the Port Arthur Refinery. In this role, he led Valero’s largest refinery, which has approximately 435,000 barrels per day of throughput capacity and employs about 850 people. Prior to his tenure at Port Arthur, Stumbo served as the Vice President and Plant Manager at Valero’s St. Charles, Louisiana refinery for seven years. During that time, the facility earned Valero’s Chairman’s Safety Award four times. Stumbo also led the refinery through Hurricane Ida and the COVID-19 pandemic and oversaw major capital investments, including the expansion of the Diamond Green Diesel renewable fuels facility. His previous experience includes operations leadership roles at Valero’s Benicia, California Refinery and the Phillips 66 Santa Maria, California Refinery, as well as engineering and operations roles with ConocoPhillips.
Stumbo holds bachelor’s degrees in chemical engineering and psychology from Oklahoma State University. Par Pacific’s President and Chief Executive Officer, William Monteleone, stated that Stumbo is a proven refining leader with nearly three decades of operating experience and a record of improving safety, reliability, and financial results. Creamer was described as instrumental in building the refining and logistics organization, with Monteleone noting his deep expertise and commitment to employees.
Par Pacific, headquartered in Houston, Texas, is an energy company that provides both renewable and conventional fuels to the western United States.
