I've used Donovan Arborists for 5 years now to help me maintain the trees on my property, including a 110 year old elm that was planted when the house was built in 1914. I've come to rely on their expertise caring for trees as well as their high-quality pruning services. read more

Last week, wet heavy snow came in fast and furiously, and the weight of the snow split a beloved cherry tree in my front yard. Not only was I devastated that I might have lost the tree - but was also worried about the tree parts that were scatter and sprawled across my neighbors' yard and our sidewalk. I called Donovan Arborists and (owner) Paul Donovan responded to me quickly, was super supportive and reassuring, and also got me into the queue the next day. In a flash he made a major stressor in disappear. Philip did a great job of cleaning up everything and then took his time to share expert advice on about how to care for my tree moving forward. It was clear that caring for trees is not just his job, but a passion. Philip actually said that being "a steward of nature" is very rewarding. This type of care what our world needs more of. Honestly - this was an exceptional experience in every way. Five stars isn't enough. read more

We have been using Donovan's for 5 years and have been extremely pleased with all of their services. We have aspen trees which are old and slowly dying and didn't want to just remove them all at once. A few years ago they recommended ways to slowly remove those trees and replace them with more reliable trees that would be happier in the city. That is happening and we are thrilled with the results. We have some beautiful trees growing now, blooming in the spring, gorgeous all summer and fall and they feed the birds all winter. Plus they are perfect for our unpredictable Denver weather. We couldn't be happier. The guys that come out are kind, cooperative, easy to work with and extremely reliable. Now our neighbors are starting to use them too. One more thing: their work with our ash tree (which we were afraid of losing) has turned the tree around. It looks beautiful and healthy again. In addition our cherry tree was badly damaged by dramatic changes in the temperature overnight a few years back and with their help, it's looking healthy and beautiful. The birds are happy to have their cherries back again! read more

They showed on time, did excellent work pruning 3 large trees and cleaned up afterwards - at a very fair price. Quite happy.

Called last week to get an estimate. Had an appointment scheduled today between 8 am and 4 pm. It's 4:30 pm, no answer at the number never called me, never texted. NOTHING!!! Took off work to get this estimate and never had the decency to contact me in any way today. Guess this is just how they do business. BEWARE!!! read more

Donovan is the best. I have 10 large trees and I've had several tree companies work on them and a few have caused so much damage my heart broke but Donovan is, hands down, the best. Donovan may be the highest estimate you get for your pruning but if you love your trees don't bother with anyone else. I really love my trees and they value them as much as I do. read more

I was extremely happy I chose Donovan Arborists since it was clear to me that the crew was experienced and used good judgement. Good price too. Don't hire a company that uses cheap labor to do an important job like maintain your trees. Contact me if you want to discuss this business. read more

Had Donovan Arborist's do a large job for us. Paul, the owner, set up an in person consultation for me and outlined our options and gave his recommendation (unfortunately this meant taking down the large locust tree in our front yard :( ). Their prices were competitive with other vendors we had bid the same project. The crew showed up on time, were very courteous and friendly and completed the work as agreed upon. They did a great job cleaning up afterwards. We would definitely use them again and recommend them to others looking for tree work. read more

I had an immense but dead willow. Near roofs and power lines yet Paul and his guys were able to remove it in a day. They referred a great stump removal guy too! Very good price and great work!! read more

Yay! We can see our house again! These guys did a fantastic job of pruning a large maple (40') directly in front of our house. It was planted 30 years ago when the home was built but never had any maintenance, says our new neighbors. They also removed a dead apple tree that was in front of the garage and cut the stump really low so that the stump grinder could do his job quickly = less $$. I was not home when the service was done but my wife was and said they were very friendly and respectful. A crew of 3-4 guys spent 3-4 hours at the house and when I cam home, the yard was absolutely clean! There is more work that needs to be done to remaining trees in the yard but we have to wait for the winter when they are dormant. We'll be using them again. read more

Tried to schedule an appointment, but was told they were a small company, too busy with current customers, and couldn't meet my needs in a timely fashion. I guess there's no reason to advertise for new customers. Will looks elsewhere for a company who needs my business. read more

We used Donovan Arborists to remove a very large cotton wood and a smaller silver maple. I had several companies provide quotes, but Donovan was the best price. They're also licensed, certified, and insured. Paul and his crew were courteous, professional, and extremely good at what they do. They were conscientious of the surrounding structures, and did a very thorough job of cleaning up. I highly recommend Donovan Arborists. I've recommended them to friends and family, and will continue to use their services in the future. read more

Legal action was threatened after you said that no one was coming back to finish the job. You unfortunately seem to have a problem keeping your facts straight. Then again your idea of customer service is blaming my kids and my dog for not seeing a utility box less than a foot away, and then calling me an a..hole. read more

See all

Donovan Arborists has taken care of all of our tree services for the past three years, and they are hands down THE BEST! They are excellent and I'd recommend them to anyone. Paul and his amazing crews have pruned my trees, they come and fertilize in the spring as necessary and have installed two absolutely beautiful trees in my back yard, one being a memorial tree which was extra special to me. The quality of their work and employees is off the charts - they're always timely and courteous. They are wonderful with the three dogs running around my yard and are kind and caring to them all. Love all of the folks we've worked with at Donavan Arborists, their trees are exceptional quality and their work is fantastic. It's evident that they are experts in their field, they have identified sicknesses in my favorite apple tree and have helped me treat it. Would highly recommend them to anyone. read more

These guys are awesome! Not only did they do a great job on my trees but they were meticulous in their clean up as well. Very nice guys who explained what they were doing to the trees and why. Do not hesitate to call this group for excellent services at good prices! read more

Excellent service from this company on our trees. We had a lot of damage to our trees from spring snow storms. The crew was hard working and friendly, and they did a great job on our trees and with clean up. read more

This company started a job and refuses to finish the work. We had a huge tree removed. They had to come back after lines where marked to grind the stump. They have given us excuses on not seeing the utility boxes, not being able to get their machine to the stump due to a plastic shed not being removed after telling me someone would help me move it as we have to move it the day of the job due to HOA, then it was they where distracted by the dog and kids, then it was no one was home even though I was home all day, no one showed up, and finally they just flat out refuse. We now have a mess of a yard and an ugly stump so we cannot begin to fix our landscape. They also did not replace the gates and fencing around our pond and those utility boxes that we put up for the safety of our young kids. read more

They did a BEAUTIFUL job on our very large ash tree. They were very meticulous and even got all of the tiny dead twigs.

Donovan Arborist was professional and gave excellent service. We got 3 other estimates for a tree removal, and theirs was the lowest. I had a coupon for another tree service that would have put it lower, but went with Donovan because of their professional courtesy. They came quickly for an estimate, left a paper copy and emailed it, and removed the tree on schedule with only sawdust. They even cut it to length for firewood for me! Payment was online and was very simple. read more
