Clayton Gray, an ISA Board Certified Master Arborist.

Clayton is an ISA Board Certified Master Arborist with nearly two decades of experience in arboriculture and forestry silviculture.

Dedicated to balancing urban development with nature preservation, he has worked in both the wild forests of British Columbia and the urban forests of the GTA.

After gaining field experience in silviculture, he studied Urban Forestry at Humber College while serving as head climber and foreman at Westwood Tree Care in Burlington. He then honed his consulting skills with the Davey Resource Group in Toronto and Hamilton.

His hands-on experience provides a unique perspective on urban forestry challenges, allowing him to develop effective solutions. With a lifetime goal of planting one million trees by hand, he is already halfway there.

Gray Matter Forestry to assist in preparing an arborist report for a municipally owned project which had a few sensitive trees to address. Clayton was extremely helpful and expedited all work as this was time sensitive. The report was extremely detailed and provided us with the exact information required to move forward with construction. I would highly recommend Gray Matter Forestry for any arborist needs.
