I am giving you a feed back on how parkers ext is doing . Roy and I are well pleased with the spray job that MATT does for us every three months. he is the most respectful and manned person i have ever seen, has such a sweet personality. he is also a hard worker and does his job GREAT at our house. if all the other workers are like MATT, you then have a great team. I hope he will always be the one to come to our house to spray, we always look forward to seeing him. GREAT job MATT ROY and LUCILLE.
