John and Mary C.
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 purchase. We have always been treated in a most professional manner, either at their shop, home or over the telephone. All repairs have been completed the first time, no returns for the same problem, which indicates the employees know what they are doing. We would epically like to express our personal thanks to Kevin for all the times he spent on the telephone guiding us through our computers, since we lack the knowledge about computers, other than to turn then on and off. Cornerstone is a most professional repair facility to deal with your computer problems and purchases, we would recommend Cornerstone to anyone.
