Steve Franzmann is a International Society of Arboriculture (ISA) certified arborist since 1992. Certified Arborists are individuals who have achieved a level of knowledge in the art and science of tree care through experience and by passing a comprehensive examination developed by the nation’s leading experts on tree care. The Certified Arborist examination covers tree biology, tree identification and selection, tree-soil-water relations, tree nutrition and fertilization, tree planting and establishment, pruning concepts and techniques, cabling, bracing and lightning protection, problem diagnosis and management, tree preservation on construction sites, climbing and safe work practices, and tree risk assessment.
Certified Arborists must also continue their education to maintain their certification and are therefore up to date on the latest techniques in arboriculture.
Certification is valid for three years, during which time the arborist must complete 30 continuing education units (CEUs) in order to re certify. Certified Arborists earn CEUs by attending seminars, studying in college courses, or completing study in ISA published magazines and books. |
