Arborists go through extensive training and testing.  A well-trained, credentialed arborist knows how to treat diseases or remove damaged limbs to maintain a tree for its health, not just for aesthetics.
Your tree took decades to grow, but a few minutes in the hands of an amateur can disfigure it. Or you may spend money treating the wrong problem.
Only a good arborist, like those at Trees "R" Us, Inc. can identify and treat diseases or pests, add bracing to large branches or add lightning protection to trees overhanging your home.  In addition the arborist should be able to show you the proper way to mulch the tree and even protect the roots during an upcoming construction project, such as a room addition or new walkway.
