After semi-retiring last year, policy expert Joe Waz has returned to Comcast full-time as its senior strategic advisor.

Waz had 17 years of service at Comcast prior to his retirement, but remained active as a consultant for the company and the rest of the cable industry, according to a blog post by Comcast executive vice president David Cohen.

“For decades, Joe’s wise counsel and thought leadership has been sought across a variety of public policy topics,” Cohen wrote. “He has helped Comcast become the media and technology leader it is today.”

Waz has served as a Senior Fellow at the Silicon Flatirons Center for Law, Technology, and Entrepreneurship at the University of Colorado, Boulder and as the founding chair of the Broadband Internet Technology Advisory Group (BITAG). He currently serves on the board of the Telecommunications Policy Research Conference (TPRC).

In his previous stint at Comcast, Waz had primary responsibility for the company’s public policy activities, and served as the executive director of the company’s political action committees, and president of the Comcast Foundation. He testified on behalf of the company before Congress and numerous federal, state, and local regulatory agencies.

Before joining Comcast in 1994, Waz spent 11 years at The Wexler Group, a government relations and public affairs consulting firm in Washington, D.C., serving as executive vice president and general counsel. He began his Washington career with Ralph Nader’s Telecommunications Research and Action Center in 1979.
