Mike Sievert

Mike Sievert leads a band of 100K+ customer-crazed disrupters and innovators changing the rules of wireless, and positioning T-Mobile as the fastest-growing company in its space for 5 years running. As President and COO, Mike is responsible for creating the company’s breakthrough market strategies and offers while taking care of 70+ million customers across all of T-Mobile’s business units and brands, in more than 16,000 retail outlets, and in every major market in the U.S. Mike’s customer experience-obsessed teams are always thinking up new ways for T-Mobile to challenge conventions while wowing customers with the next innovation. They’re passionate about working smart and fast to deliver experiences no one saw coming. By eliminating two-year contracts; doing away with data overage charges; introducing fair and transparent phone and upgrade plans; launching unlimited music, video, and LTE data; and rolling out “Team of Experts” customer service, his team is changing wireless for good. Mike joined T-Mobile in 2012 as Chief Marketing Officer and became COO in 2015. In 2018, he joined the Board of Directors and was appointed President of the Company. 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. 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.
