All they can do is butcher trees. They do not know a thing about proper pruning.\r
I spoke with (and showed the end product to) a Certified Aborist after they pruned some trees at my apartment complex. She told me they actually did more harm than good, and in her opinion they didn't have a clue about pruning.\r
They also damaged a couple of pieces of private property in their path of destruction!\r
Stay safe, stay away from Twin Cities Tree Service!
Cons: Dangerous to trees and humans!
