Forensic investigation and testimony in tree-related litigation. Clear, credible, and prepared for cross-examination.

06

Tree Inventories

Comprehensive site surveys for municipalities, HOAs, and property managers. Data-driven management plans that actually get followed.

Independent by design.
Credible by necessity.

Most arborists who sell tree work have a financial incentive in every recommendation they make. We don't do tree work. We don't sell removals, pruning, or planting. Every opinion we deliver is based solely on what the tree needs — and what serves you.

This isn't a feature. It's the only way we know how to operate with full credibility in every conversation we enter.

How it works
A

Reach out

Tell us what you're dealing with — a permit deadline, a liability concern, a tree that looks wrong. We'll tell you if we're the right fit.

B

We assess

On-site inspection, measurements, and documentation. We use industry-standard protocols so findings hold up to scrutiny.

C

You get the report

Written clearly, on time, formatted for the audience — whether that's a planning department, an attorney, or you.

How we work

Transparent pricing

We quote before we start. No surprise invoices, no scope creep.

Fast turnaround

Most reports delivered within five business days of the site visit. Rush service available.

Plain-language writing

No jargon for jargon's sake. Reports that a homeowner can read and an attorney can use.

Local knowledge

We know the North Bay. Every jurisdiction has its own tree ordinance. We've worked with all of them.
