I cannot do justice to the overall quality of the service, but I also want to pay homage to the kindness and the generous treatment that I received, in turn, from Adam, Glenn, Justin and Will. It is my pleasure and indeed my responsibility to commend each of them and Blue Dot for having such reputable competent and committed employees.

We are a long time Blue Dot customer and have always been pleased with our service. The latest visit was no exception. Our service rep, John M. was prompt, friendly and knowledgeable. He performed our service check and answered all of our questions. He also left us printed material and price quotes on possible future purchases. We would be happy to have John M. as our permanent Blue Dot service rep.
