Ian Irwin - Instructor

Ian Irwin

Certified Instructor

Ian Irwin has been in the woods as long as he can remember. First picking up a chainsaw when he was thirteen he understands its value as an essential tool in the forest. Now able to concentrate most of his logging to family land located near his home in Granby Vermont, he is able to work in the woods most of the year. With rising costs of equipment and instabilities in wood markets he feels strongly that now as much as ever the safe and efficient use of the chainsaw is an important way to manage our timber resources economically. Most importantly he simply loves falling trees. When Ian is not logging or instructing, you’ll likely find him somewhere in the world shearing sheep.
