Defects, Decay And D49

Published on

One of our most current Lunch 'n' Learn presentations. This presentation is the result of many observations we've made regarding properties with high risk trees gone either ignored or unnoticed. The D49 portion of it comes from a recent case where workman's compensation fraud has apparently flooded the tree trimming industry and we've taken the opporunity to educate our customers about the risk of using tree trimmers who do not classify their employees correctly. Please let me know if you are interested in this presentation.
