Where we have not used them first hand, when one of our neighbors partially lost one of their Great Oaks they sent this recommendation - "We live on __________ and you may have noticed the crane and crew on our street all day today. We had an emergency removal of 2 large branches from our 500 year old Live Oak in the backyard. We are in awe of the effort and the thoughtfulness that went into our job. We can't recommend them highly enough - tree lovers and true professionals! "
