Sievert was was most recently the CEO of tablet gaming firm Discovery Bay Games, but has served in mostly marketing exec capacities during his 22-year career, including positions at Clearwire, AT&T Wireless, Microsoft, IBM and Procter & Gamble.
Andrew Sherrard, T-Mobile's acting CMO since Brodman left the company after 17 years, will resume his duties as svp of marketing for contract business for the company. T-Mobile is the fourth-largest carrier when it comes to wireless subscribers, trailing Verizon Wireless, AT&T and Sprint Nextel.
In a prepared statement, John Legere, CEO of T-Mobile USA, suggested Sievert was the right choice to catapult his brand forward. "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," he said.
