About Root Cause
Most tree work starts with a solution. We start with the problem.
Root Cause is an ISA Certified arborist practice in Mesa, built on one habit: understand what's actually going on with a tree before deciding what to do about it.
Diagnose before prescribe.
How we think about trees
Most people point at a tree and name a solution right away — it needs to come down, just top it, cut it back. We slow that down. Before recommending a single cut, we want to understand what's actually going on: the structure, the history, and how the tree got to where it is.
In the Valley, that story usually starts with water. Too little stresses a tree; too much quietly rots the roots — and either way, the canopy is where it shows up. So irrigation is often the first thing we check, not the branches.
Only once we understand the problem do we write the plan — and it's always specific to that tree, on that site. The goal isn't to do less work or more work. It's to do the right work, and to be able to tell you exactly why.
We'd rather take a little longer to understand a tree than be quick to cut it.
Once the cause is clear, the plan almost writes itself.
IDENTIFY → UNDERSTAND → PRESCRIBE
Good tree care shouldn't be the exception.
Why it matters
You've probably seen it without thinking about it — a tree outside a gas station or a strip mall, topped flat or cut down to a few stubs. It reads as normal because it's everywhere.
Most of the time, that isn't carelessness. Good tree care is genuinely hard to find, the fast version is cheap, and when no one has shown you the difference, you take what you're given. We'd rather show people the difference — not by criticizing whoever made those cuts, since most were never taught otherwise, but by doing the work properly, explaining the reasoning, and letting the tree be the proof.
Here's the part worth knowing: tree work isn't licensed in Arizona the way contracting is, which means almost anyone can offer it — and plenty do, faster and cheaper. What you're paying for with a certified arborist isn't a logo. It's a diagnosis grounded in training, a written record you can hand to a buyer or an HOA, and someone accountable for the recommendation. Cheaper is easy to find. Accountable is the rare part.
That's the standard Root Cause is built to hold — and if doing it this way, one honest assessment at a time, helps raise what the Valley expects from tree care, even better.
Anyone can pick up a saw.
Diagnosing, documenting, and standing behind the work is the trade.

Behind Root Cause
Root Cause is led by Anthony, an ISA Certified Arborist who came up in this trade from the ground up — beginning in 2020 across commercial, residential, and HOA work, including years inside the Valley's large landscape operations, managing tree programs across commercial and HOA portfolios. The certifications came as stepping stones along the way, roughly one every year and a half: certified tree climber in 2023, certified arborist in 2024, and prescription pruning qualified in 2026 — each a milestone earned on the way to the next, with more still ahead.
Most of it was self-taught, but taught the hard way — by paying attention to every cut. Maintaining the same trees and tree groups year after year meant the results came back around to be seen, learned from, and corrected. Few things sharpen judgment like watching how a tree answers a decision you made a year earlier.
Bonsai shaped how we approach full-size trees — reading structure, understanding how a tree responds, and making only the cuts that are necessary, each one with a reason behind it. Structural pruning informed by bonsai discipline.
It adds up to a practice worth standing behind: slower, more careful, and accountable to the tree first. Rooted in Mesa, built for the desert.
Today that same standard extends to whole communities — dedicated tree management, separate from the landscape contract, with one arborist responsible for every tree. Community tree management →
