Kudos to our Security Consultant Mark Gustin on converting another satisfied customer!"I just wanted to write and give a compliment to your company and our new security system. We switched from another company that we were having nothing but trouble with and what a difference it was dealing with Guardian. The salesman Mark, the installer and the equipment are all top notch. We have only been a customer for less than a week but we are very impressed so far." Joel W. - Bay City, MI
