One of the ways that Ryan, owner of Lawrence Arborists is involved in the International Society of Arboriculture community is that he is an Evaluator for the ISA Certified Tree Climber credential. This past week, he was in St. Louis leading the training for a group of prospective evaluators. This work helps to increase the access to the credential by bringing on new evaluators to help host regional trainings and certification exams. It was a beautiful day and a great training group!
