"We hired Jose to install a new phone system at my office and I cannot say enough good things about his work. He arrived on time, was professional, and made sure that everything was working before he left. We needed new cabling done, phones to be connected as well as a database hardwiring. I would absolutely recommend Diversified to anyone that is looking for someone who is knowledgeable, professional, and reasonably priced."
