DALLAS — Joseph Scalzo has been promoted to president and chief operating officer of Dean Foods Co. Mr. Scalzo most recently was c.o.o.

“Since I named Joe chief operating officer late last year, I have been impressed by his quick and thorough analysis of the business and the depth and breadth of mission-critical initiatives that are underway,” said Gregg Engles, chairman of the board and chief executive officer. “In this short time frame, we have benefited greatly from his ability to build teams and establish a turnaround mindset.”

In the new position, Mr. Scalzo will oversee the company’s operational turnaround and near-term strategic initiatives as well as its business units and key functions.

“Joe has focused on getting us organized around fewer, bigger initiatives that can extend our low cost position in a meaningful way,” Mr. Engles said. “With Joe’s leadership, we are moving forward aggressively to advance our turnaround and position Dean Foods for a strong future. This promotion is in recognition of what he has accomplished.”
