G. Michael Sievert, insider at T-Mobile US

G. Michael Sievert Insider Information

CEO of T-Mobile US
Mike Sievert is president and chief executive officer of T-Mobile and is a member of T-Mobile’s Board of Directors. Mike leads a customer-crazed team of disruptors and innovators, working tirelessly over the last eight years to change the rules of wireless, resulting in T-Mobile becoming the fastest-growing company in the industry. He most recently served as president and chief operating officer of T-Mobile.

As CEO, Mike is responsible for leading T-Mobile into the 5G future as it combines operations with Sprint to supercharge the successful Un-carrier strategy. His focus is on ensuring that T-Mobile is the fastest growing company in its space, with the best network and best experiences, delivered by the best team. To do this, Mike and team are all about unlocking the potential of the combined companies’ increased scale, which is expected to result in over $43 billion in synergies, enabling lower costs and the ability to deliver even more to customers, at lower prices. A centerpiece of that focus is building the world’s best 5G network—with massive increases in network capacity and 5G coverage. Every day, Mike’s priority is on cultivating T-Mobile’s culture and building a company that is world-famous for putting customers first, treating them right, and changing the rules in their favor—all with one simple goal: creating the most loved brand in the history of the telecom industry.

Mike has been actively involved in all of T-Mobile’s significant corporate decisions since he joined T-Mobile in 2012 as chief marketing officer and since he became COO in 2015. In 2018, he joined the board of directors and was appointed president of the company. Prior to being CMO at T-Mobile, Mike joined Clearwire Corporation, now part of T-Mobile, in 2009, serving as EVP and chief commercial officer. Mike was instrumental in building T-Mobile’s “Un-carrier” strategy to solve customer pain points, an approach that has been the foundation for T-Mobile’s unprecedented growth over the past seven years. He worked alongside prior CEO John Legere since 2012, transforming T-Mobile into the enormously successful Un-carrier, all while pursuing the Sprint merger, to cement T-Mobile’s ability to continue to be a disrupter well into the future.

Mike believes that great customer experiences can only come from a great company culture. Over the years, Mike has been extensively involved in leading and shaping T-Mobile’s customer-obsessed “Un-carrier” culture—one that encourages communication, diversity, opportunity, collaboration, and transparency—all of which are vital to T-Mobile becoming a bigger and more disruptive force for consumers and businesses in the wireless industry.

Mike also serves on the board of directors of Shaw Communications in Canada. Prior to joining the Un-carrier, Mike had a nearly 25-year career in marketing, technology, and entrepreneurship. Over the years, he has served in various roles, including EVP and chief sales and marketing officer at E*TRADE, EVP and chief marketing officer at AT&T Wireless, and corporate vice president of the Windows Business Group at Microsoft. He started his career in marketing at Proctor & Gamble and IBM.

He’s an avid aviator and mariner, and an enthusiastic supporter of conservation and the environment—especially in his adopted home of the Pacific Northwest. He’s a proud husband and father to two boys in their 20s. Mike owes his success to daily doses of a perfectly crafted dark roast French press, the source of all his earthly power.
