I chose Mark Mortensen when I was walking through my neighborhood and saw him and Andy working together on a neighbor's tree. I could tell by how they spoke to each other how knowledgable and professional they were. When Mark came to give us an estimate, we were impressed with his background and body of work. We hired him, and he and Andy came and did an outstanding job for us. They were fast, efficient, friendly and tidy. We can't say enough good things about them! We plan to hire them again this winter when we need more things done.
