Certified Arborist List

The following arborists are ISA certified and licensed to perform tree work on trees in the right-of-way in the City of Spokane.

The City requires that any pruning, planting, or removal of a tree in the public right-of way (ROW) must be done by a certified arborist who is licensed to perform commercial tree work within the City of Spokane.  Below is a list of arborists that homeowners can choose from to perform tree work on trees in the ROW adjacent to their property.  These arborists are very familiar with our required permitting process.

What does it mean to be ISA certified?

Certified arborists are individuals who have achieved a level of knowledge in the science of tree care through at least three years of work experience and have passed an examination on a variety of tree care knowledge. To learn more about the International Society of Arboriculture credentials visit ISA's website.

Certified arborists perform a wide range of tree management services. Not all arborists provide all services, or are experienced in them. Good arborists will only perform accepted practices. Practices such as topping a tree, removing an excessive amount of live wood and using climbing spikes on trees that are not being removed, are not accepted practices.

The companies and individuals listed may provide these and other tree care services: tree pruning, planting and removal; cabling; fertilizing; root pruning; vertical mulching; diagnosis and treatment for pests and diseases; tree appraisals; hazard tree evaluation; and stump removal. As with any professional service, we encourage you to ask questions about licenses, insurance and check references. Hiring a certified arborist does not guarantee proper tree care, but it is one step you can make to improve the proper care and ongoing health of your trees.
