About

TreeXP acknowledges tree climbing for recreation, sport, scientific research and of course for tree care. Using non-invasive climbing techniques and appropriate climbing gear, a climber is able to ascend and descend to and from the tree canopy, as well as, traverse from tree to tree, with the intention of having minimal to no impact on the trees themselves. Like coral reefs, tree canopies are full of life and incredible beauty. Tree climbing is similar to rock climbing, but instead of depending on a rock wall for support, tree climbers are connected to living beings, by way of a climbing line.

John Greer is the founder of TreeXP. He’s also involved with the Global Organization of Tree Climbers (GOTC) and the Tree Climbers Rendezvous. He worked in the banking and real estate industry in Southern California, before relocating to Western Washington and starting a web development company. In addition to tree climbing, John’s passions include photography and writing. Since 2015, John has received professional tree climbing instruction from both The Cornell Tree Climbing Institute and Tree Climbing Planet.

Tree people, aka: treepls, are true inspirations for everyone.  Scientific research shows the positive physiological changes that occur in our bodies when we climb trees and these effects can last long after the climb itself.

Thanks for being a part of nature and one with all, including our most precious resources, our trees.
