"I had a great experience working with Great Rock on my new home project. Fredy is very knowledgeable regarding all aspects of his material, fabrication and installation.  Katie is masterful in coordinating selection, installation and office activities.  The installers were courteous, careful and professional during delivery and installation processes.  I will definitely be going back to Great Rock for my future projects.
