In this one-day course, Certified Tree Experts Ted Szczawinski and Steve Chisholm will walk you through the step-by-step process of identifying a hazard, dealing with the hazard, properly documenting your findings, and then recording the work you performed. The class will include hands-on field instruction, and it will detail the three-point tree rating system used by many top professionals.
