Steven Sterin will join the company as executive vice president and chief financial officer, effective Aug. 18, and Cynthia "CJ" Warner will join Tesoro as executive vice president, strategy and business development, effective Oct. 6.
Scott Spendlove, who has served as the company's CFO since May 2010, is leaving to pursue other interests.
"I thank Scott for his many contributions to Tesoro during his 12-year tenure and wish him all the best as he moves onto other endeavors," said Tesoro President and CEO Greg Goff.
Sterin comes to Tesoro from Celanese Corp., a global technology and specialty materials company, where he held financial leadership positions of increasing scope, including senior vice president and CFO for the last seven years. He previously worked for Reichhold Inc. and Price Waterhouse LLP.
"With his demonstrated track record of financial and business leadership, Steven will be a great asset to Tesoro. He will be a key member of the executive team that will help us deliver on our ambitious plans," Goff said
Warner will join Tesoro from Sapphire Energy, a global provider in the development of renewable crude oil from algae, where she was president, CEO and chairman of the board over the past five years. Prior to joining Sapphire Energy, she held numerous leadership positions with BP, including group vice president of global refining and group vice president of health, safety, security, environmental and technology.
"CJ is an accomplished executive with a strong track record of delivering results. I am very pleased to have her join Tesoro and our leadership team at this exciting time for our company," Goff said.
