BOISE, Idaho — Albertsons Cos. has announced a number of promotions, including that of Wayne Denningham to the new role of president and chief operating officer.

He had been executive vice president and COO. Bob Miller remains chairman and chief executive officer, a role he has held since April 2015.

The company also named Geoff White to the new position of president of own brands, and promoted Mike Withers to East region executive VP of retail ­operations. Replacing Withers as Jewel-Osco president is Doug Cygan, who had been the division’s VP of marketing and ­merchandising.

Denningham will continue to lead store operations, with added oversight for marketing and merchandising, supply chain, manufacturing and integration, all of which will continue under their current leadership.

“This is the strongest leadership team I’ve worked with in my 50-plus years in this industry,” said Miller. “I asked Wayne to join Albertsons LLC in 2006 to lead our Rocky Mountain division. Since that time, he’s led three different divisions, helped to negotiate and manage some of our most significant acquisitions, and successfully turned around some of our toughest assets. He’s a remarkable leader with tremendous grocery retail acumen.”

Denningham began his career with Albertson’s Inc. in 1977 as a clerk and served as a district manager before being named president of the Rocky Mountain division and, later, the Florida division. He was subsequently promoted to regional president for five divisions, and then served as both executive VP of marketing and merchandising and executive VP of operations before leaving in 2004.

He joined Albertson’s LLC in 2006 and served as president of the Rocky Mountain, Florida and Southern divisions over the next seven years. In March 2013, he was named president of the Southern California division following the acquisition of 877 stores from Supervalu and, in January 2015, he assumed the role of South region COO following the merger with Safeway. He was named executive VP and COO in April 2015.

White will be responsible for furthering growth, development and innovation of store brands and will lead Albertsons’ culinary kitchen and technical center.

Withers will lead Eastern operations, while current executive VP for retail operations Susan Morris will lead the West region. Jim Perkins, executive VP of retail operations special projects, is focused on targeted initiatives to accelerate growth. All three will continue to report to ­Denningham.
