On July 4th, in the evening hours, our server went down. This affected our entire operation. Making a call to Cornerstone, we to their “after hours” agent. In a matter of minutes, David Moore (President of Cornerstone) called back and was on his way to our location. David came prepared based on our phone conversation, but our server could not be revived. David and Kevin Estep worked tirelessly at getting us a new server and getting us back up and running in a timely manner. We can’t say enough about the sense of urgency that they had and the quality and determination they put into restore our business operation. We would recommend David Moore and Cornerstone Technology Services, LLC highly to anyone.
