The Jones Group is losing its chief marketing officer, Stacy Lastrina, who has been with the company for 21 years. Lastrina, 48, joined the company in 1991 as director of marketing for Nine West Group, which The Jones Group bought in 1999. She eventually moved up to executive vice president of marketing and creative services at Jones, and took over her latest position in 2009. The company doesn't plan to hire a replacement; instead, Richard Dickson, president and chief executive officer of branded businesses at Jones, told WWD that he and Stefani Greenfield, chief creative officer, will handle Lastrina's job, which includes overseeing marketing, public relations, store design and national advertising. Lastrina will stay on in a consulting role.
