The Altitude Arborist Difference

Tree Services Across the Colorado Front Range


Plant Health

We use treatments that are scientifically proven to target the pests impacting your landscape while minimizing the impact to the beneficial insects. We do everything in our power to make sure we are diligent in protecting pollinators while completing our treatments.


Caring for your trees and shrubs is not only important for the look of your property, it’s also good for the environment. You need someone who will take care of your trees and shrubs gently and properly while teaching you how to maintain them.


Have debris from damaged trees or broken branches? If you have a sizable amount of tree debris to clean up, we’ll come to your property clean up your lot quickly and efficiently. Instead of giving up your weekend to clean up the debris, let our team handle it right away.

Tree Pruning & Planting

We plant according to the International Society of Arboriculture’s best management practices including the proper hole depth and width, backfilling, staking and mulching. We help ensure planting success by applying a root stimulating fertilizer at the time of planting and offering continued fertilization services for future growth.


You don’t want to risk the health of your trees or the safety of your property and loved ones to someone who is under-qualified. Your trees are a long-term part of your landscape and proper care and pruning will help your trees enhance your property for longer.

Sometimes the lowest quote can end up costing you more down the road if the tree is improperly pruned or damage or injury occurs on your property by a company without the proper insurance. You want someone who values the safety of your property, pets, and family as we do. Our prices are fair and competitive with other qualified companies. Our customers know when they choose Altitude Arborist, their trees and their property are in the best hands.


Altitude Arborist is a full-service tree care company serving North Denver homeowners. We help you care for and protect your trees while following safe work practices and using the highest quality of customer service.

Stump Grinding

If a customer would like to see the entire tree removed including the stump we can accommodate that! We can grind any size stump. Generally stumps are ground 6-8 inches below the surrounding landscape grade. For many stumps, the grinding will remove a majority of the root ball and some of the lateral roots.

Tree Removal

We own a bucket truck with a 65 foot reach to aid us in the removal of trees where access is adequate. We have arborists on staff capable of hand climbing trees in more remote areas of the landscape where our bucket truck cannot be utilized and the tree is safe to climb and remove.

I used Altitude Arborist back in July of 2018 to remove an 80' cottonwood. They did a thorough and complete job in a timely manner - when they said they would. I would recomment to a friend IF Hunter Thowndson is the owner of this company.

Hunter has been feeding my trees (9) for 4 years. This past year they needed trimming. At first, I was worried about too much trimming, but after a year, I realized it was done correctly. My trees look healthy and great.

Altitude Arborist has a professional, responsive and, hard working team. They were friendly, quick, and the clean up was fantastic! I've already booked a second job with them.
Hired them to remove 3 giant willows from my property. They did a great job and had perfect communication through the whole job. Hunter came out for the estimate and he was a pleasure. Great guy and super knowledgeable! Would hire again for sure. Thank you crew!
