Macy's has tapped Martine Reardon as its new chief marketing officer.

The announcement comes amid a series of senior executive moves at the retailer, prompted by the retirement of Ron Klein, the retailer's chief stores officer. Peter Sachse, who was named Macy's first CMO in 2003, will take Mr. Klein's place. In 2006, Mr. Sachse temporarily relinquished his role as the head of marketing when he became chairman-CEO of Macys.com. He reclaimed the CMO role in 2009.

Mr. Sachse's responsibilities will be split between Ms. Reardon and Jeff Kantor, who will become chairman of Macys.com. The moves will all be effective as of Feb. 13.

In her new role, Ms. Reardon will be responsible for all marketing, advertising, creative development, social media, cause marketing, brand public relations, tourism marketing, customer insights and data analysis. She will also join the retailer's executive committee. Both Ms. Reardon and Mr. Kantor will report to Jeffrey Gennette, Macy's chief merchandising officer, who is assuming additional responsibility for overseeing marketing and Macys.com.

Ms. Reardon, who was named an Ad Age Woman to Watch in 2009, has been exec VP-marketing for three years. She has held a variety of positions at Macy's , as well as various department store entities that were merged into Macy's . Ms. Reardon began her career in special events at Abraham & Straus in Brooklyn in 1984.

"Our organization is deep and experienced, which facilitates our ability to crisply execute strategies and to move quickly to capitalize on new opportunities as they arise," Terry Lundgren, Macy's CEO, said in a statement.
