TREEKEEPER TREE SERVICE INC was established in 1985 by Dan Sorenson. He is an ISA certified arborist. To obtain certification he had to pass a lengthy exam covering a wide range of topics that included such things as tree biology, pruning, plant health care, tree risk assessment and safety. A continuing education program is required to maintain certification. This assures you that you are hiring someone from the local Portland area with up to date tree care knowledge and experience. We are also qualified to do Tree Risk Assessment. ISA qualification for arborists. Tree risk assessment can provide tree owners and risk managers with the information to make informed decisions to enhance tree benefits, health, and longevity. We go out on a limb to provide customer satisfaction and are licensed, bonded and insured.

Dan rescued our cat Max at the 60 ft level in a 70 ft. tree. Then he ground down a bunch of stumps and really fixed up our front yard. Dan was fast, friendly, and did an excellent efficient job. We will use him again for sure!!
