I have been using Paramount for 6 years. The principle reason is because of my technician, Marty. He is professional, affable, and takes care to do his tasks correctly and goes far beyond the "extra mile" to ensure that everything is accomplished correctly and to my satisfaction. If I have any difficulty with household insect problems during interim periods, all I have to do is make a phone call and he will arrive to take care of the problem as soon as he is able.
