" Would like to say we are overall very impressed with the service we receive from Cornerstone. They have been servicing our trucks for a couple of years now and have done a fine job. When we have had issues they have always taken care of them in a professional and timely fashion. Knowing that we can count on them means a lot to myself and our organization everyone knows time is money and the one thing I know is that I do not have to worry about the conditions of our trucks. Thank you...  "
