TreeXP acknowledges Recreational Tree Climbing as a sport. 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. Like coral reefs, tree canopies are full of life and incredible beauty. Recreational 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, founder of TreeXP worked in the banking and real estate industry in Southern California, before moving to Bainbridge Island, Washington. In 1998, John founded Web Shui LLC, a web design and development business. His hobbies include photography and writing articles and books about things he’s passionate about.  Beyond recreational tree climbing, John loves playing tennis and golf, as well as, non-competitive adventure sports, including hiking, skiing, mountain biking, stunt kite flying, surfing, scuba diving, skateboarding, snorkeling, kayaking, windsurfing, paddle boarding, motorcycling and even parasailing.  Experience wise, since 2015, John has received professional tree climbing instruction from The Cornell Tree Climbing Institute and Tree Climbing Planet.

John Gathright’s pioneering work, along with others who recognize and promote non-invasive tree climbing not only as a form of physical therapy and recreation, but as a way to connect with and be one with nature in a deeply fulfilling spiritual sense, are true inspirations for everyone.  John’s ongoing efforts are helping many young adults with physical challenges get into trees. He has also proven through scientific research, the positive physiological changes that occur in our bodies while we actually climb trees.


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