ABOUT THE ARBORIST
A federal prime built around one discipline.
As a federal hazard tree contractor, The Arborist performs vegetation risk work on federally managed land, since 2024.
One discipline, applied across five operational environments.
The Arborist exists to solve a problem most contractors will not touch: hazard trees and vegetation risk on federal land where the site cannot shut down, the resource cannot be damaged, and the window to do the work is measured in hours rather than weeks.
The firm operates as a federal prime, not a residential tree service that occasionally bids government work. Every contract action in the portfolio was performed as prime, across four agencies and three departments, with the same crew, the same credentials, and the same method on every site.
The work spans five operational environments, from post-disaster hazard mitigation to precision extraction inside archaeological zones. What connects them is a single standard: the site's purpose governs the method, and the method is documented before the first cut is made.
The ISA Board Certified Master Arborist credential is held by fewer than 1,300 professionals worldwide. The Arborist maintains BCMA supervision at the company level.
