T-Mobile USA is losing its chief marketing officer, Denny Marie Post, who is stepping down from her position. According to a spokesman for T-Mobile, the former Starbucks executive is looking to start a consultancy outside the wireless industry.

Post’s decision to leave the company was a personal one and there was no immediate information from the spokesman about when the position would be filled or who would assume the CMO’s duties in the interim. The spokesman added that Publicis will continue to be the company’s brand and advertising partner.

Prior to joining T-Mobile in 2008, Post was the senior vice president of global food and beverage for Starbucks.
