Our experience with Northwest Aboriculture was outstanding from start to finish. I appreciated Trent's willingness to take on a challenging job and his ability to deal with a neighbor who had some detailed concerns. The team of five men showed up on time, worked together flawlessly, did an artful job pruning a huge hedge and a number of tall trees, and cleaned up so there was no detritus remaining. This was the second time we used NW Aboriculture, and I feel lucky to have found them. They are very busy, but in my opinion it is worth the wait.

Very helpful. On time. Did pruning of spindly alder trees that required a bucket truck. Also chipped and removed a large amount of brush. They may not be the cheapest, but are very complete and professional. I also got a quote for a large number of 150 FT plus cottonwood trees leaning toward power lines which required use of a large 50 ton crane. So they can do very large difficult jobs.

We have many large trees and periodically needed tree work done over the years, and have called upon this firm before. NW is the best we have ever had on all counts, and just yesterday had their service once again. Not only have they been responsive in emergency situations, but have the experience to advise, perform, and clean up all at reasonable rates.
We couldn't be happier.

The entire experience with Northwest Arboriculture was top notch and I would highly recommend their services. I had eight trees removed from my property and my experience with Northwest Arboriculture was an excellent one. The entire crew of six were highly capable safety-minded individuals who showed up on time and were extremely organized and efficient in their methodology in removing the trees. They moved the cut trees safely to the wood chipper and cleaned up the property so no signs of debris was left. The team was very friendly, respectful and efficient at every stage of the process.

The NW Arboriculture team was booked out a bit when I called earlier this year, but their thoroughness and professionalism was worth the wait.
Knowledgable staff, thorough clean-up of the work site and on-time completion of work make them a must-book for any future tree needs I have.

We had some unhealthy trees that needed help. Matthew was very knowledgeable and gave us options which we discussed. The quote was detailed and accurate with notes on what we could do on our own.
The crew arrived on time and quickly completed the job with detailed cleanup. I know who to call for my tree needs in the future.

Trent and his team did a fantastic job pruning our very large and tall hedge. They clearly understand trees and treat them with respect. They pruned our hedge with an artfulness that exceeded my expectations. After pruning, they hauled away a huge amount of greenery and left our lot looking fantastic. Since they had to use my neighbor's driveway to get access, I was a little worried about how our neighbor would react, but he told me he was as pleased as I was with the work that was done. I will definitely have them do all of our tree work.

Northwest Arboriculture runs efficient, thorough and friendly crews!
We have a pretty tight area with very tall and hazardous trees that needed to be taken down. Northwest Arboriculture has been very conscientious about the other greenery, structures and septic drain fields while being very time efficient. I am amazed at how quickly they've worked!
We got half a dozen or so bids on the job before selecting Northwest. We got a few lower bids, a few higher bids and a few somewhat bizarre suggestions on how to deal with the trees. We are very glad that we went with Northwest!

I should have written this review years ago. In 2012 we had a very large cedar that cracked and needed to be removed before it fell onto my house. This was not a straight forward job. The cedar spit into 3 and the part that needed to be removed cracked off of the main base. The section of tree in question was 80+feet tall and 5 feet in diameter. Trent and his crew has to use a crane to secure the tree, cut, and then lift each section over my house. The process was exciting and terrifying to watch. The guys were amazing and left my house looking like nothing happened.

We had him come out to check the trees around the house to make sure we're safe in the next storm. He was friendly and very thorough. I appreciated the fact that he explained everything so I can understand. He made suggestions, but didn't try to upsell me by saying I NEEDED to do anything. I would definitely suggest Northwest Arboriculture.

In the recent storms we had a giant branch fall on our house and pierce our roof. Trent and the crew were awesome and prioritized getting it resolved for us before rains started again. Trent communicated with us during the day about his timing. When the team arrived they were super efficient and friendly, managing to get the branch removed and everything cleaned up even though it was late at night. Thank you!!

Trent and his team were fabulous and super professional. We were impressed with how efficient they were. We had a tree that was tilting badly and had to be removed before the forecasted windstorm. The guys were literally in and out in approximately 15 minutes, and they even cleared the wood chips and debris from our neighbor's driveway (since they had to access via their driveway). Would absolutely engage them again in future and recommend them to our neighbors!

Owner Trent and NW Arborculture staff did an excellent job on our project from start to finish. They were on time, communicated well regarding the project, completed all that was outlined on the bid, protected shrubs and property, and did a great job on the cleanup afterward.

I'd consider NW Arboriculture one of the most considerate, professional, polite, hard working, tidy, organized and cooperative companies I've ever seen operate. They arrive, introduce themselves, do their work and clean up every twig of debris before leaving. I'd recommend them very highly.

I am most impressed with the knowledge and expertise of the folks at Northwest Arboriculture! This most recent round of work was to repair some unfortunate pruning on the part of a different tree service, and to undo some over-enthusiastic planting on my part... My trees now look superb, and the ones planted in the wrong place that were threatening to remove my roof (!!) have been neatly removed. I am very excited to work with NW Arboriculture to get my yard to match my internal vision, only with their expertise to make better choices and create a healthy and sustainable urban landscape.

As a Landscape Professional for over 30 years, Trent and his crew are the ONLY tree care service I recommend to my clients. He has done me right every time and I fully trust his judgment on every tree care issue that arises for my business.

Trent and his crew is professional, well equipped, friendly, efficient and clean. I hired him because his offer was reasonable and he was the only one out of three Arborists I have met that found my cherry tree has damages by Cherry Bark Tortrix. Will not hesitate to call them again when I need any tree services in the future. Highly recommend Trent and his crew to viewers who need the service.

Very competent guys and do a clean job. We needed to have cedar tree removed that was extremely close to the house.

They came on time, were friendly, very efficient and thorough. They were done within an hour and cleaned up the spot nicely before leaving.

Definitely highly recommended, will call them if I need any more tree services.

I needed a Tree Service to take down some trees. I had a couple tall trees too close to my house. They were shedding huge limbs during snow and wind storms. Each time a limb crashed down it was causing damage to my roof and gutters. I like trees but sadly these particular trees had to come down. I own a chainsaw but no way was I going to attempt this - time to call in the pros!

Northwest Arboriculture is a small professional, efficient, courteous crew of tree professionals. It was amazing to watch them work. I got a free zero-pressure estimate which ended up being the least expensive of
