We had a network issue where the speed was not acceptable for our new computers.  Darren sent someone out within hours after my first call to him. Although they were unable to take care of the issue that day (we were too busy to bring down the network to fix the problem), Darrencame out at a pre-arranged time the following week (when we weren’t so busy) and took care of the problem in a very short time period. Darren is professional, he listens carefully, and does a thorogh job correctly.
