WSD has learned that John Grant, Treasury Wine Estates' vp of marketing for the Americas, is leaving the company to "pursue external opportunities." Recall, John was placed in this role almost four months ago during the restructuring of TWE's global leadership team. He will be replaced by Barry Sheridan, formerly vp of brand marketing at TWE. Barry has been with TWE for eight years and has a strong marketing leadership background, including previous senior roles at Diageo and Revlon. He will report to Sandra LeDrew, cmo for the Americas and serve on the Americas leadership team. Additionally, he will report to cmo Simon Marton "to ensure global brand alignment."
