About Us

isa_logoarboristlogo

mm smallI'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.

One thing that separates Mortensen Tree Service from the competition is that, I am personally there through every phase -- from answering the telephone, to conducting the evaluation, performing the work, and providing additional advice for the care of the trees. We are very proud of our safety record serving our clients in the Denver metro area for more than a decade, (since 1995) with no personal injuries or property damage.

Mission Statement

  • Provide the finest quality tree service
  • Respond promptly to all inquiries
  • Operate all phases of our operation in a very professional and safe manner.
