North American TCC Operations Committee

The North American Tree Climbing Championship (NATCC) Operations Committee’s purpose is to provide a competitive but educational opportunity for working arborists in North America to demonstrate and exchange new climbing techniques, safe work practices and increase the interaction between various firms, ISA components and members, and provide positive public exposure for the profession. This is accomplished through a competitive event held in North America, culminating with the winners being sent to represent the North American Region at the International World Championship held prior to the ISA Annual Conference.
