Patrick is an awesome arborist, hands down! I have a couple of young Monterrey Oak trees and one of them lost its leaves while the other seems healthy. I took some pictures and emailed him to ask if it was serious or not. He responded quickly and was very helpful. He seems to really care about trees and is not just out to make money. My question was resolved with a simple answer and even some additional advice on how to care for my trees. In the future for any of my tree needs I will definitely call Austin Tree Specialists.
