Delek makes leadership changes, splits COO roles between new hires

Delek US Holdings Inc. made changes to its senior leadership team, splitting the duties of chief operations officer with the departure of Todd O’Malley.

Joseph Israel has been named executive vice-president, operations for Delek US and Delek Logistics effective Mar. 27. Israel and Patrick Reilly, who was named executive vice-president and chief commercial officer on Mar. 1, will split O'Malley's responsibilities.

Israel will be responsible for refining operations at Delek US and for logistics operations at Delek Logistics Partners LP. Chavez will report to Israel and will oversee refining operations at Delek US.

Israel holds over 25 years of energy experience and recently served as president and chief executive officer of Par Petroleum LLC, a subsidiary of Par Pacific. He also held leadership positions at Hunt Refining Co. and Alon USA, which were acquired by Delek US in 2017.

Chavez brings over three decades of refining experience, most recently with TotalEnergies SE where he held the position of general manager, Port Arthur refinery and petrochemical complex.

O’Malley, who departs the company to pursue other opportunities, joined Delek in 2021 and was named chief operating officer in March 2022 (OGJ Online, Mar. 28, 2022; Mar. 1, 2021).

Additionally, Tommy Chavez was named senior vice-president, refining operations, effective Apr. 10. Nithia Thaver, the company’s former executive vice-president and president of refining, left Delek to pursue other opportunities.

O'Malley and Thaver will be available for the transition through September 22, the company said.
