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.

Kind of frustrated with this company. Called a few times to try and get a free estimate. Each time they took my info and said someone else would get back to me to schedule an appointment. No one ever did get back to me.

We had two huge Cottonwoods that needed to be removed and, knowing it was going to be a big job, got quotes from 5 other local companies. Hunter's price for both trees, including stump grinding, was around what most other companies quoted us for just the largest tree. We back on to town property and Hunter completely took care of the permits for access to the greenbelt for removal. The team was prompt, professional, responsive, and left the yard in perfect condition. We highly recommend them and will definitely use them for all of our future tree care.Updated 6/22: Once again, we had a WONDERFUL experience with Hunter and his team. Scheduling and getting a quote was easy. Their team was extremely communicative. They did a great job removing an aspen tree that was directly next to our house for a great price. We've also recommended them to many family and friends in recent years, who have had similar experiences. Honestly, between price and quality of service we are unlikely to ever seek out another company for this type of work.

Had a maple feed that was struggling because the poor clay soil here blocks the tree from absorbing magnesium and iron. Also had in ash tree injected to stop ash borers from killing the tree. Altitude arborist is really good to deal with as far as the treatments go only time will tell if they're effective. I'm giving them five stars because of their customer service so far.

It's time to start caring for your tree and we can help!
