Consulting Arborists/Plant Pathologists

A plant pathologist is trained to interpret and diagnose the structural and functional changes caused by diseases and environmental issues in plant and tree tissues. If you suspect your trees have a health issue, it may be beneficial to have a plant pathologist or consulting arborist provide a health inspection. Since our inception, our consulting arborists have received training from our company founder and Plant Pathologist, Kevin Bassett, and our additional Plant Pathologist, Russell Peters.
