Member of the International Society of Arboriculture

2010 ISA-​RMC Arborist of the Year

An arborist is a specialist in the care of individual trees. Arborists are knowledgeable about the needs of trees, and are trained and equipped to provide proper care.

Pruning or removing trees, especially large trees, can be dangerous work. Tree work should only be done by those trained and equipped to work safely in trees.

Well cared for trees are attractive and can add considerable value to your property. Poorly maintained trees can be a significant liability.

Meet the Business Owner

Mark M.

Business Owner

I’m Mark Mortensen, ISA Certified Arborist and owner of Mortensen Tree Service. I have been involved in the «green industries» since the early 1970’s and have worked for several companies in many different capacities, including nurseryman, landscaper, landscape design, turf management and arboriculture.

I formed Mortensen Tree Service, Inc. (aka Mortensen’s Property Services, Inc.) in 1996 to offer superior tree service in the Denver metro area. It all begins with a proper evaluation of the tree’s condition. This is a face to face meeting, discussing the goals and the clients desired outcome, determining if it realistic and/​or, ethical, explaining in detail how we will accomplish those goals, and then following through, with the desired and expected outcome, in a timely and professional manner.

Excellent efficient service. Very pleased with the work. Mark is a competent well trained arborist. Have previously tried to do this ourselves and the end product shows. Better to have someone well trained do this. Very grateful and satisfied. Definitely will use again and can’t recommend him enough!

Today I spoke to Mort himself and was very disappointed in the way he handled the phone call. I’ve never used Mortensen Tree Service before, but was needing to have someone come and look at a tree in my backyard that needs help. Not only did Mort not know what he was talking about, he said to me «well I’ll pass.» Pass on what… the business! Wow so unprofessional and rude. I would never use Mortensen Tree Service, nor recommend them to anyone. If he’s in the business of helping trees, but he’ll pass. That says a lot about him and his lack of passion for trees. What a jerk!

Mark’s been a force for good in our neighborhood for some time. In the Blizzard of 2003 and its aftermath, Mark was out there working to save the trees that could be saved, with his trained arborist’s eye, and cutting down the ones that couldn’t before they could fall on someone. Since he helped us then, he’s been keeping our trees healthy and well-​mannered.
This year we lost two more trees that had to come down. Mark and his team kept the noise and disturbance to a minimum, and, which is very important, cleaned up beautifully afterward, rake clean or better, and made sure I was pleased with the job. Mark’s prices are reasonable, and he gets back to you quickly when you want to consult him about what to do. He’s earned those five stars over a long and valued relationship.

We were having some problems with our trees when we first called, Mark. They had totally over grown the area and were pushing up against the windows screens. I was very concerned about trimming the tree so that it was clear of the window screen, but I didn’t want it to loose it’s nice full look. After the service, the trees are beautiful. They still have that full look, but they are now completely clear of the windows. They’re not lopsided at all.
Shortly after that, we had a number of Aspens, between 20 and 30 feet tall, that have died and needed to be cut down. A few of these trees overhung an awning and I was concerned about damage. They brought down the trees with no problems, and helped give us some ideas as to what we can do with the now vacant location.
They even helped answer a few other questions we had about trees on our property. We definitely recommend Mortensen and will continue to use them for any future needs.
