The annual list recognizes individuals shaping policy and driving progress across the region. Stegmaier was included again this year in the Technology and Telecom category for his work helping leading technology companies, their customers and users, regulators, legislators and others address the most pressing technology issues of the day including artificial intelligence, privacy and security, online safety for children, biometric, competition policy, online speech and related consumer protection issues.

When learning of the recognition, Stegmaier said: "I enjoy rolling up my sleeves with technologists, business people, regulators and consumer advocates to make a difference on complex technology issues. I love being reminded that we can do good and do well for everyone and many hands make light work."

Based in Washington, D.C. for more than 30 years, Stegmaier brings a deep personal commitment to client service, an understanding of the interplay between innovation and its consequences, and an appreciation of how to bridge gaps between consumer protection and evidence-based policymaking. He focuses his practice on corporate governance, data and intellectual property, internet issues and digital assets, especially as they relate to privacy, security and accountability.
