We just had a huge tree removed from the front of our house on Portland Street because the roots were destroying our sidewalk so we hired Mark Davin 412-297-3000 certified Arborist and tree climber who does pruning,removal,leaf removal,fertilizing diagnosis,and consulting. He did such a wonderful job! He was extremely nice and his price was far better than others. He cleaned up everything after he removed the tree and huge stump. I highly recommend Mark. If anyone out there is in need of any of these services, please contact Mark and tell him Francine recommended him!
