Tree Pruning should be done by a qualified Arborist, as improper pruning could significantly reduce the life of your trees, or kill them completely! An arborist should never use "gaffs" or "spikes" to climb a tree that's being pruned, this wounds the tree, and creates a vector for bugs or disease.

There are many benefits to tree pruning: removal of dead or decayed branches, storm damage, cross leading branches, wind-sail, and improved storm resistance. 
We often are called to fix work done by other companies that performed work like "topping," or other improper pruning techniques. Often the damage has already been done, and sometimes it's too late to do anything about it. 
Our team of arborists will assess your needs, and make the proper recommendations.
