“Nationwide trimmed and stumped some trees. It was very good. They did what they said they would when they said they would. They did the job the way I wanted it, and they were very professional. I'd give them an A. It was excellent, and I'm very satisfied. I would recommend them.”
“They're very good. I'm very pleased with them. They cut my trees down. They did an excellent job. I would say they're the best they could be. They get an A.”
“They explained in detail what they were going to do. They removed a tree and took the stumps out. They also trimmed two trees and cut a tree down. They were very professional and had good conversation skills. I'd rate them as an A+ overall.”

“Very professional. Good conversation. They explained in detail what they were going to do and they did it. They removed a tree and took the stumps out. I'd give them an A+ overall. They also trimmed out two trees and cut a tree down. I'm looking at another tree and about two weeks ago I made sure I had their card, so I could call them back.”
“It's been a while, but it was fine. They did some tree trimming. I don't remember if they took one out or not. I know there were several that needed trimming. I would give them an A. They cleaned up nice and they were quick and careful. They were very good. It is very likely I would recommend them.”
“It was fine. They just took out a couple of shrubs. I'd give them an A. I would probably recommend them. It's a sentimental thing. I got them and then I completely forgot about them, so I don't know if I would recommend them or not.”
“They were fine. They were on time and they did it and got it done. They trimmed some trees. I'd give them an A.”
“I have recommended their company to someone I know who had scheduled to get his trees cut down that weekend. Tree removal and stump grinding. I'd give them an A.”
