Look first, cut second.

Two brothers, one family business

We are Devin Warrick and Alex Moon, two brothers. We started this as weekend work in 2023, went full time this year, and the two of us still own it and run it between us.

How this started

Warrick Brothers is named after exactly what it is. Devin Warrick and Alex Moon founded it together in 2023, licensed, bonded and insured from the first day, and the two of us still own it and run it between us. It says A FAMILY BUSINESS on the side of the chip truck because there was never a version of this that was not one.

Devin's uncle was a climber, and splitting firewood for him as a teenager was the first tree work he ever did. His own route through the trade after that was the long one. Canvassing, then groundwork on a crew, then assisting a project manager and shadowing estimates, permitting and scheduling, then back on the crew because that was where he was useful. The turn came at a larger company where he worked alongside certified arborists for the first time and properly learned tree biology, which is the difference between knowing how to cut a tree and knowing what the cut will do. He carries the ISA Certified Arborist credential and the Tree Risk Assessment Qualification, and that is the standard this company reads a tree by.

Alex founded the company with Devin, and the climbing, the rigging and the crew on site are his. He runs estimates the same as Devin does, and if you read our Google reviews his name is in a lot of them, usually attached to a tree that had to come down over a garage or a fence. Between the two of us there is close to 20 years of experience in tree work.

We ran it on weekends for the first couple of years while we both worked elsewhere. It stayed consistent enough for long enough that this year we took it full time and bought our first big chip truck, and today it is the two of us and one crew of three. That is the whole story. There is nothing older or larger in it, and we would rather say so than dress it up.

Devin is our certified arborist, and he learned this trade on a crew before he learned it in a book. He climbed, ran ground, shadowed estimates and permitting, then worked alongside certified arborists at a larger company and studied tree biology properly. He carries the ISA Certified Arborist credential and the Tree Risk Assessment Qualification, and that is the standard he sets for how this company reads a tree. Every estimate we write is written against it, which is why the answer you get is about what the tree needs rather than what is easiest to sell.

  • ISA Certified Arborist
  • Tree Risk Assessment Qualified
  • Estimates and climbing

I grew up around this work. My uncle was a climber, and splitting firewood for him is how I started. I came back to trees through groundwork, then climbing, then estimating and permitting, then tree biology alongside certified arborists at a larger company.

I hold the ISA Certified Arborist credential and the Tree Risk Assessment Qualification, and I set the standard every estimate this company writes is held to.

From the reviews

Devin and Alex did an amazing job for me. One tree in particular, I knew needed some expertise to fell it without a problem.

I would rather tell you a tree can stay than sell you a removal it does not need.

  • Climber
  • Runs jobs and crews
  • Estimates

Devin and I started Warrick Brothers together in 2023, as weekend work while we both had other jobs, and we took it full time this year. I climb, I run the crew on site, and I run estimates the same as he does.

Between us there is close to 20 years of combined experience in tree work. Most of what we take down in this county comes out in pieces on ropes because there is a fence or a roof underneath it.

From the reviews

Alex and his crew did a great job taking down a big Madrona that was growing over the neighbors garage and a big fir tree.

I would rather take an hour longer and put every piece exactly where I meant it.

  • A certified arborist's standard

    Devin holds the ISA Certified Arborist credential and the Tree Risk Assessment Qualification, and every estimate we write is made against the framework he was trained in.

  • A written estimate before we cut

    You get an itemized estimate after the visit, in writing, before we schedule a saw. We have to see the tree before we can put a number on it.

  • The yard the way we found it

    We chip, haul and rake as we go. Our own chip truck means the brush leaves with us when we do.

The chip truck

We bought our first big chip truck this year and had it wrapped in August. We call it our moving billboard, which is fair, but the real point of it is that a crew with its own chip truck can take the brush away as it goes rather than leaving a pile on your lawn until somebody can come back for it. It is the piece of equipment that turned this from weekend work into a business that finishes a job in a day.
