T-Mobile Touts New Chief Marketing Officer

As part of the ongoing effort by the mobile operator to take a bigger share of subscribers away from the top three carriers in the United States, T-Mobile is giving its marketing presence a big boost of fresh talent this week.

T-Mobile has appointed Michael Sievert as the company’s s new chief marketing officer. And he reported for duty this morning.

Before coming to T-Mobile, Sievert spent 20 years in high-ranking marketing positions at such places as Clearwire, AT&T Wireless, Microsoft, IBM, and Procter & Gamble.

Acting CMO Andrew Sherrard will now go back to serving as senor vice president of marketing for T-Mobile’s contract business.

“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,” says John Legere, president and CEO of T-Mobile USA. “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.”
