Beech trees Fagus sylvatica) and Plane trees ( Platanus). I just love their trunks and nature’s artistry. Espessially, from all of my years in southern France, the scaling bark of the plane trees.


Highest tree you have climbed? 

Not that high- yet. I am a ground man that came in to this business at 50 years old J, and I am just learning the art of climbing. One of the arborists in my company is my cousin Patrick Coulter, who is of course a ETW-certified arborist with 17 years of experience, is teaching me the basics of climbing.

Have you had any close calls? If yes, what happened? Knock on wood (arboriculture bad  joke) so far nothing, at least nothing I can brag about.

My talents are not that hidden since I am a super outgoing person J.. But I am a trained sommelier and I can weld!


When you’re not climbing trees what are your other interest/hobbies.?

I love to play tennis and road cycling!
