Dear Chris,

I am writing to you regarding my experience with KorTerra. Due to new Gopher State One Call requirements, it was necessary for our company to find a new way of processing our locate tickets.

We had met with Rick Olson on a couple of occasions to discuss the possibilities that KorTerra could offer our company. In October 2005 we implemented the KorWeb program for use. It was a fairly easy transition over to the new system and broadened our ticket processing options. We appreciated Rick following up with us several times to make sure everything was going smoothly. Of course, Erik Chamberlain made sure it was. Although all of your support team has been wonderful, Erik has been very helpful with every question and concern we have had regarding the program. He also kept us updated with the progress of the report program that we purchased to be designed specifically for our needs. Even though every computer program has its own quirks, Erik and your programmers have been very responsive to our suggestions and requests for changes. We especially love that we never hear “why would you want to do that”. Your team is very eager to help out and make the KorWeb program the best that it can be to fit our needs.

Choosing KorTerra has really been a positive change for our company. We are very excited with the new ideas your company has come up with to make our jobs easier and look forward to implementing the new programs as they are available. Thank you.

Sincerely,

Ruth Klick
