Knowledge & Experience You Can Trust

An arborist is a specialist in the care of individual trees. Arborists are knowledgeable about the needs of trees, and are trained and equipped to provide proper care. Mark Mortensen is among the best and has worked in the field since 1995.

Pruning or removing trees, especially large trees, can be dangerous work. Tree work should only be done by those trained and equipped to work safely in trees.

Well cared for trees are attractive and can add considerable value to your property. Poorly maintained trees can be a significant liability.
