Why certified

What ISA Certified means for your trees

The International Society of Arboriculture certifies arborists who have documented experience in the field and passed a comprehensive exam covering tree biology, pruning, diagnosis, soil management and safe work practices. The credential has to be renewed, with continuing education required to keep it.

We are also Tree Risk Assessment Qualified (TRAQ), an ISA qualification in a standardized method for judging how likely a tree is to fail and what it could damage if it does. We hold the ISA Prescription Pruning Qualification as well, which covers writing pruning specifications suited to an individual tree, along with horticulturist accreditation through the Indiana Nursery & Landscape Association.

For you, that means advice grounded in how trees actually grow, from where to make a pruning cut to which species suits your site.
