We’re Cornerstone Connectivity.
We believe that fast, reliable internet isn’t a luxury: it’s the foundation of modern life. It’s how families stay connected, how businesses grow, how students learn, and how rural communities compete on a level playing field with anywhere else in the country. That’s what we’re here to provide, and it’s what drives every decision we make.
Cornerstone Connectivity serves residential and business customers across Kentucky, Tennessee, Illinois, and Alabama, delivering high-speed fiber internet, mobile service, home security, and voice services to communities that have counted on us for generations.
Who we are.
We’re a tech-forward and human-centric telecommunications company. That means we stay ahead of the technology curve: investing in fiber infrastructure, expanding our service area, and building the networks that tomorrow’s smart homes and businesses will run on. But it also means we never lose sight of who we’re doing it for.
Our customers aren’t just account numbers. They’re our neighbors. They’re the people we run into at the hardware store and the football game. They’re the families who’ve trusted us to keep them connected through every stage of their lives. That relationship isn’t something we take lightly.
Where we came from.
Cornerstone was built on the foundation of two companies with deep roots in their communities — West Kentucky & Tennessee Telecommunications Cooperative, which has served customers across Kentucky, Tennessee, and Illinois since 1951, and Ardmore Telephone Company, which first connected the Ardmore, Alabama community back in 1908. Together, those two organizations represent well over a century of showing up for people that larger providers overlooked.
