School of Trees

School of Trees is built on real-world mentorship and hands-on training, not shortcuts or theory alone. Our goal is to pass down proven climbing, rigging, and tree care techniques through practical instruction, safety-first practices, and field-tested experience from certified arborists providing professional arborist services in Fort Hunt, Virginia. Whether you’re new to tree work or refining advanced skills, this platform focuses on proper training, critical thinking, and respect for the craft—while also providing clear, responsible homeowner care tips to help property owners better understand tree health, maintenance, and when to call a professional local arborist in Alexandria, Virginia . Be sure to verify an

ISA-Certified Arborist  credentials.

 School of Trees, operated by Sean Harman’s Tree Care, LLC, serves as a supplemental, experience-based arborist education platform providing field training for members of our professional staff, and does not issue professional certifications or replace formal credentialing through organizations such as the ISA. 

 School of Trees emphasizes ethical decision-making, risk awareness, and adherence to accepted arboricultural standards. Training is intended to supplement field experience and professional development, with safety and judgment prioritized over speed or production.
