Mike Sievert, President and Chief Executive Officer

Portrait

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 seven years to change the rules of wireless, resulting in T-Mobile becoming the fastest-growing company in its space. He most recently served as President and Chief Operating Officer of T-Mobile. As President and Chief Executive Officer, Mike is responsible for leading T-Mobile into the 5G future as it joins forces with Sprint to supercharge the successful Un-carrier strategy. His focus will center around unlocking the potential of the combined companies’ increased scale, which is expected to result in over $43 billion in synergies, create lower costs and offer the ability to deliver better services at lower prices for consumers. A centerpiece of that focus will be the transformational nationwide 5G network that the T-Mobile team is building; it will deliver massive increases in network capacity, drive innovation, and enable consumers to get both a better value and a better network. Sievert and team will continue to cultivate T-Mobile’s culture that is world-famous for putting customers first, treating them right, and changing the rules in their favor — with the goal of 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 has been instrumental in building T-Mobile’s purpose-driven strategy to address 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. He also worked very closely with John Legere in directing the approval and integration efforts for the pending merger with Sprint, to create the New T-Mobile. In addition, Mike has been extensively involved in shaping T-Mobile’s internal customer-obsessed “Un-carrier” culture — and is building on a company culture that encourages communication, diversity, opportunity, collaboration and transparency — all of which are vital to T-Mobile remaining a disruptive force 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 as 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 Procter & 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.

Portrait

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 seven years to change the rules of wireless, resulting in T-Mobile becoming the fastest-growing company in its space. He most recently served as President and Chief Operating Officer of T-Mobile. As President and Chief Executive Officer, Mike is responsible for leading T-Mobile into the 5G future as it joins forces with Sprint to supercharge the successful Un-carrier strategy. His focus will center around unlocking the potential of the combined companies’ increased scale, which is expected to result in over $43 billion in synergies, create lower costs and offer the ability to deliver better services at lower prices for consumers. A centerpiece of that focus will be the transformational nationwide 5G network that the T-Mobile team is building; it will deliver massive increases in network capacity, drive innovation, and enable consumers to get both a better value and a better network. Sievert and team will continue to cultivate T-Mobile’s culture that is world-famous for putting customers first, treating them right, and changing the rules in their favor — with the goal of 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 has been instrumental in building T-Mobile’s purpose-driven strategy to address 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. He also worked very closely with John Legere in directing the approval and integration efforts for the pending merger with Sprint, to create the New T-Mobile. In addition, Mike has been extensively involved in shaping T-Mobile’s internal customer-obsessed “Un-carrier” culture — and is building on a company culture that encourages communication, diversity, opportunity, collaboration and transparency — all of which are vital to T-Mobile remaining a disruptive force 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 as 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 Procter & 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.
