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. Mike and his 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.

He also worked very closely with John Legere in directing the approval and integration efforts for the 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 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’s an avid aviator and mariner, and an enthusiastic supporter of conservation and the environment—especially in his adopted home of the Pacific Northwest.
