Sean Harman is an ISA Certified Arborist (MA-6197A) based in Alexandria and Fort Hunt, Virginia, providing arborist-led education and field-based insight into tree biology, pruning practices, tree risk, and complex removals throughout Northern Virginia.

This channel explains how tree problems develop over time, why some pruning cuts fail to compartmentalize, and how proper access, precision, and biological understanding influence long-term tree structure and public safety.

Content is filmed on site during real evaluations, climbing work, and crane-assisted removals. Videos emphasize correct pruning principles, CODIT (Compartmentalization of Decay in Trees, as described by Dr. Alex Shigo), and risk-based decision making for hazardous trees.

Sean Harman’s arborist perspective on wind-related tree failure and emergency risk mitigation has been featured by WJLA (ABC 7).
