We had Mortensen Tree services out to take down a tree in the back on our alley, and to prune up two large trees in our front yard. They were quick and efficient in taking down the back tree, they cleaned up afterward, and they were very friendly. In the front yard I was nervous about having the trees pruned because they create beautiful shade for us in the summer. Mark listened to me and was very careful to take my concerns into consideration. The trees look healthier and cleaner and I couldn’t be happier!
