Glen F. Post, III

The CenturyLink career of Glen F. Post, III has spanned four decades. He joined the company in 1976, was elected to the Board of Directors in 1985 and has served as Chief Executive Officer since 1992. Since that time, he has led the company’s strategic positioning and directed all acquisitions and divestitures.

He also led CenturyLink’s transformation over the last several years into a global network provider and managed hosting and IT solutions leader. Under his leadership, CenturyLink has become a leading provider of high-speed data, managed hosting, IT and voice services across the U.S. and in select international markets, through strategically investing in its advanced fiber optic network and complementary advanced technology capabilities.

Glen has always led CenturyLink with a focus on delivering high-quality products and services to its customers; enhancing the communities it serves in a meaningful way; and creating a dynamic work environment for employees.

He has maintained a disciplined approach to operations leadership and strategic acquisitions and to utilizing CenturyLink’s strong cash flow and financial strength in driving long-term shareholder value. The 2009 acquisition of Embarq Corporation more than tripled the company’s revenues and customer base, and the 2011 acquisition of Qwest more than doubled CenturyLink’s size again, transforming CenturyLink into one of the leading communications companies in the United States and a recognized leader in providing networking solutions.

CenturyLink’s 2016 annual revenues were $17.5 billion, up from $360 million in 1992 when Glen was appointed CEO.

The 2017 acquisition of Level 3 Communications further transformed CenturyLink, making the company the second largest domestic and the third largest international communications provider to global enterprise customers. CenturyLink’s increased scale, combined service offerings and enhanced business focus solidifies the company’s position as a global network solutions leader.

Under Glen’s leadership, the company established and then expanded the CenturyLink Clarke M. Williams Foundation. This Foundation is dedicated to improving the well-being and overall quality of life of people in the communities CenturyLink serves. Named after CenturyLink’s founder, Clarke M. Williams, the Foundation is endowed by CenturyLink and provides funds for numerous community and educational initiatives, including the company’s Backpack Buddies Food Drive, which has provided over 56 million meals to people in need through local food banks over the past eight years.

Glen serves on the National Security Telecommunications Advisory Committee (NSTAC) and a number of other Boards and Foundations. He previously chaired the FCC’s Communications Security, Reliability, and Interoperability Council.


Glen holds a Bachelor’s Degree in Accounting and a Master’s Degree in Business Administration from Louisiana Tech University.
