DAT has done a beautiful job designing and installing the complex electrical systems in our new home. In addition to sophisticated lighting, backup generator panel, remote monitoring, the entire electrical team from DAT was a joy to work with. They know what they're doing, they are smart, know how to explain choices well, and they're solid, kind, dependable people. I observed them in rather tense situations created by others and they were unfailingly pleasant, honest and honorable. I can recommend them enthusiastically.
