We began with the goal of providing affordable DSL high-speed internet service to Rural Maine, especially Western Penobscot and Southern Piscataquis counties and other such areas not served by either Verizon/FairPoint, Cable or other ISPs.
But Cornerstone is not just an internet company. We also provide high-quality phone service (business and residential) within most of our service area. Ask about our packages that include high-speed internet and phone...and we will save you money over your traditional phone service.
We are constantly expanding, so if you would like to know if we can serve you, contact us at 564-5000, and one of our friendly staff members will see what we can do for you.
We are locally owned and operated. All of our employees live within the Cornerstone Communications service area.
For whatever season of life you find yourself in, Cornerstone wants to be there for you!
