David is awesome! Each and every time he arrived early, and he is such a happy individual. Such a rare trait these days, I think. He was very efficient and his bills were always extremely fair, given the time it took to do the work. I called him recently because I though the ballasts needed to be replaced in one of the garage light fixtures. When he arrived (early), he examined the fixture, noting that the florescent bulb had not been "inserted" completely into the ballast, so he "snapped" it into place and the light came on immediately. When I went to pay him, he said "there was no charge".!!! He further said he just likes doing nice things for nice people. I've used him for 5 years. David Tow is an honest, hard-working, ethical businessman. And a good person. There are so few of them out there nowadays I feel.
