Stuart Corvin said in the statement that he will continue to take a lead role in strategic planning, the financial integration of Cal-Steam and Wolseley, as well as customer and employee relations. Dana Corvin will continue her role in the human resources area. The rest of the Cal-Steam management team and associates will remain in place.
