Peter opened a recreational tree climbing school and it attracted climbers from other sports. The gear and techniques did not always fit the needs of climbing something as fragile and alive as trees. Safety was always a concern and many techniques were downright dangerous. That's when he saw a need to build a foundation of standardized technique and tools to protect the climber as well as preventing injury to the trees being climbed. It seemed even more important to start with a solid groundwork if there was a chance of the sport entering mainstream society.

Some of the members climb as professionals but the majority are people who love getting up in trees. No prior experience is needed. Some people join to learn new techniques. Some join to meet other climbers. Others purchase membership for friends they know who climb.
