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.

The family of Wholesome Foods would like to thank Cornerstone for the great job at Dean Pence’s recent funeral. We had a small church and had to broadcast the serivice live to another building. Everyone said they could hear just fine and see the service. It was great. I called them on Wednesday and they had it all done in time for funeral Friday with a reasonable price.

As a customer of Cornerstone for over 9 years, we would like to express our thanks for all the service provided for the repairs and new purchases. We have always been treated in a most professional manner, either at their shop, our home, or over the telephone. All repairs have been completed the first time, with no returns for the same problem, which indicates the employees know what they are doing.
We would especially like to express our personal thanks to Kevin for all the time spent on the telephone guiding us through our computers, since we lack the knowledge , other than to turn them on and off.

President, R.A.C. Security Systems, Inc.


Mr. Moore has been our network administrator for the last four years, beginning with Shenandoah Technology Systems, of which he was a partner, and now with his new company, Cornerstone Technology services. In that time he has maintained our systems better than our previous provider.

He consistently procures the most economical software and hardware packages that best suit our needs and future growth.

Mr. Moore has corrected our security issues. Our security now exceeds the standards recommended by HIPAA. He responds to our calls promptly even though we are not a large account.

I would recommend David Moore and Cornerstone Technology very highly.
