US department store retailer Macy's Inc is reshuffling its executive leadership team ahead of the pending retirement of its chief stores officer Ron Klein at the end of March, after 36 years with the company.

Peter Sachse, chief marketing officer and chairman of macys.com, will succeed Klein as chief stores officer on 13 February. He will be responsible for the nationwide portfolio of Macy's stores, as well as the region and district stores organisation and visual merchandising.

Sachse also will retain responsibility for the company's omnichannel strategy, which brings together stores, online and mobile capabilities. He will remain a member of the company's executive committee and continue to report to Terry Lundgren, chairman, president and CEO.

The changes will also see other executives take on new roles.

Chief merchandising officer Jeffrey Gennette will take on extra responsibility for overseeing marketing and macys.com. He will closely coordinate those functions within the company's My Macy's localisation and omnichannel strategies. Gennette will remain a member of the company's executive committee and continue to report to Lundgren.

Jeff Kantor, president of merchandising at macys.com, will become chairman of macys.com. Kantor and Kent Anderson, president of macys.com, will continue to oversee Macy's Internet business and play a key role in the omnichannel strategy. Kantor will join the company's executive committee and report to Gennette.

And Martine Reardon, executive vice president for marketing, will succeed Sachse as chief marketing officer.

"These changes reflect the strength of our senior-level talent and the teamwork that drives our company's key growth strategies - My Macy's localisation, omnichannel, and MAGIC Selling customer engagement." Lundgren said.

"Our organisation is deep and experienced, which facilitates our ability to crisply execute strategies and to move quickly to capitalise on new opportunities as they arise."

He added: "We salute the outstanding contributions that Ron Klein has made to our company for nearly four decades."
