Everett Lewis, who worked as an executive in Hawai'i's oil refining industry, has been named executive vice president and chief operating officer of Tesoro Corp.

San Antonio-based Tesoro operates Hawai'i's largest refinery.

Lewis, with 38 years of refining experience, joined Tesoro in 1999 as senior vice president for strategic projects. Before joining Tesoro, he worked in and consulted for the refining industry, including managing the BHP refinery in Kapolei that was later bought by Tesoro. He holds a bachelor's degree in chemical engineering from Iowa State University and a MBA from the University of Hawai'i.

"We are a dynamic organization that challenges our employees to take on new responsibilities," said Bruce Smith, Tesoro's chairman, president and chief executive officer. "We believe these moves provide tremendous development opportunities for our employees and strengthen the company's management for our shareholders."
