“I have worked with Michael since he started in business and it has been a win win situation for both of us. He does what he says and scheduling is a priority. His quality of work is A+. He is a manager along with working alongside his crew when needed. He is always in touch with the project and what is going on so he can be in control.

I would recommend CMC Electric and Michael, to anyone who is looking for an honest, straightforward contractor.”
