Services
Collier Arbor is proud to be a division of Bartlett Tree Experts, and our staff now has the backing of an international tree-care company and tree research laboratory to help continue providing excellent tree service and shrub care in the Portland, Oregon area. We are committed to helping local residents and businesses maintain beautiful, healthy trees and shrubs from our Clackamas office.
Our arborists are balancing plant health, safety and artistry when pruning and shaping your plants from specimen shrubs or prized lace leaf maples to the largest shade and evergreen trees. We prune to emphasize a tree's natural shape. If the tree has structural problems, we can cable it to increase its safety.

In the Willamette Valley, our most common deciduous native tree is the bigleaf maple. It gets its name from the size of its leaves. In Latin, the species name Acer macrophyllum means big leaf: macro meaning large and phyllum meaning leaf. The bigleaf maple has the largest leaf of any maple in the world, measuring 6-12 inches across and having five lobes, resembling a human hand.

We used Bartlett’s in 2017 and had a great experience. They were professional, responsive, and did a great job. In spring of 2020, we contacted them to trim some trees and take one out. Someone came out and we had a great discussion, and he said someone would call us in the fall. No one did. By the time we got someone on the phone, they couldn’t come until New Year’s Eve.
When they did come out, they did the tree trim but took out the wrong tree- the one they took was an established rhododendron, instead of the scrub tree that clearly needed to go. They couldn’t do the stump removal because

Positive: Professionalism, Punctuality, Quality, Responsiveness, Value
Very fast and efficient. Very likable crew and representatives. I seriously recommend these guys. Had a very small area to work in on a very large tree. No damage at all and did the work on the hottest day of the year with no complaint.

Had 3 trees with different problems. The sick cedar in front yard was removed, stump so thoroughly ground out that a new tree can be planted there. Huge old maple in back threatened neighbor's house. Pruned for safety and done without cabling. 3rd tree even trickier-an old red plum which anyone would say is a candidate for removal but it's a habitat for birds. My arborist understood and thinned it out so it can die a little slower. He left plenty of stubs and cavities for habitat and the birds and I could not be happier.
As a professional gardener myself, I was very concerned on all counts. These
