Estimator & Arborist Tree Trimmer (Production Arboriculture)

Treesources is seeking an experienced Estimator who is also a seasoned, hands-on arborist tree trimmer. This is a dual role: you will scope and estimate production-arboriculture work *and* strengthen the team with production arboriculture support — assessing each job through the eyes of someone who has climbed, rigged, and made the cuts. You will conduct site visits, produce accurate and well-documented estimates, and build complete work packets that crews mobilize on without guesswork — and you will be able to step into the field to demonstrate, train, or support crews on the tools when the work calls for it. This is a high-impact role for a working arborist who estimates with precision because they know firsthand what the job takes.

Key Responsibilities

• Conduct site visits to assess trees, access, hazards, and site conditions from a working climber/trimmer's perspective, and translate them into accurate, buildable project scopes.
• Prepare complete, defensible estimates of labor, crew hours, equipment, materials, traffic control, and debris disposal for production arboriculture work (pruning, removals, cabling/bracing, and related services).
• Produce comprehensive job hand-off packets for field crews — documented scope, site maps, photographs, annotations, and clear work instructions — so each mobilization is fully prepared.
• Perform and lead hands-on tree work as needed — climbing, aerial-lift, pruning, and removals to ANSI A300 / Z133 standards — to set scope, demonstrate technique, train crews, and support production in the field.
• Build and maintain estimates and work orders in the company's field-service management system (ArboStar), keeping it the single source of truth for every job.
• Track estimated-versus-actual scope and hours on completed jobs, and use the findings to continuously improve estimating accuracy.
• Coordinate closely with production crew leads to hand off work cleanly and incorporate field feedbac...
