“One of the cornerstones of our success has been our ability to organically develop a strong leadership team,” said Debra L. Reed, chairman and CEO of Sempra Energy. “We and our board of directors spend considerable time and effort identifying talented leaders within the organization and exposing them to different aspects of our business. Today’s appointments represent another step forward in our succession planning process.”
