I bought a home in Charlottesville with a small lot and two large(80+ year old) maple trees. After getting quotes from three firms to remove the dead one and trim the other, I picked Big O as the best value. The tree removal was a particular complex job as it required a large crane to remove pieces from my yard(up and over a shed). They were easy to work with in terms of scheduling and understanding of expectations. I was impressed with both their efficiency and attention to detail. They have an experienced crew who seems to know what they are doing.
