My husband and I worked with Jason J from Cornerstone and he was factastic. We could not have asked for a more professional, efficient and fast install from another company. From start to finish everyone from Jason to to the roofers were exceptional. Even our insurance adjuster was happy that we used Cornerstone. If you want quality work with a great team use Cornerstone Construction.

I cannot say enough good things about Cornerstone! Building a new dental office is a huge undertaking due to the amount of plumbing, electrical and coordination between all the moving parts in a tight space. I was advised to not go the design-build route at the beginning of this project, but I truly wish I had just let Cornerstone quarterback this from the start and pick their own architect/engineer.
They have proven again and again that they only have my best interest at heart. They came in exactly at my budget and were very cognizant of it throughout the entire process. Terry runs an honest, transparent, caring and detail-focused company that's committed to high quality and ensuring the client is happy. They are everything you could want in a GC and more, which I believe is pretty rare to say about a contractor at the end of a project. Ben, Tyler and Christian are all excellent in their respective positions and were there for me every step of the way. I will forever be grateful to them! If you have any type of commercial project, this team is the way to go!

We could not be happier with the work that Cornerstone Company did for our new chiropractic office. Terry met with us several times through the planning process, his team was always professional and attended to every request we had. They walked us through the entire process to make sure we knew how each step would go. Our project was done on time and under budget and we owe it all to Terry, Christian and the rest of the Cornerstone Company. Well trust them with all of our future projects!
