T-Mobile Names Former Microsoft Executive Mike Sievert as Marketing Chief

T-Mobile said on Friday that it has hired former Microsoft, AT&T and Clearwire executive Mike Sievert to run its marketing operations.

“Mike is a unique creative genius, and his track record as a disruptive force in tech and telecom couldn’t be better suited to our plans to redefine wireless as America’s un-carrier,” newly hired T-Mobile CEO John Legere said in a statement. “This is a critical and incredibly exciting time for T-Mobile as we race forward with our network modernization and LTE launch in 2013, ramp up investments in re-launching our brand, and begin to shake up the U.S. wireless market.”

The move also comes as T-Mobile works to complete its merger with prepaid carrier MetroPCS.

With Sievert’s hiring, T-Mobile said, acting Chief Marketing Officer Andrew Sherrard will return to his post as senior vice president of marketing for T-Mobile’s contract business.

Most recently, Sievert served as CEO of Discovery Bay Games, a Seattle-based mobile gaming company.
