About Us

Our Purpose:

Pursuing GREAT experiences through our love of trees.

The core behaviors of our people:

  • A Desire for growth in our calling
  • Thoughtful and caring
  • Being of service
  • Fun loving – laughing at ourselves

Caring for the urban forest is our mission — we seek to always improve our environment. Even when managing an epidemic such as Emerald Ash Borer, we diligently look for safe, effective, and organic solutions.

Get in touch with us and we’ll send out a certified arborist to inspect your trees and make recommendations that make sense for the health of you and your property.

We are tree people, but we’re also people. From our first contact, consultation, and estimate to our comprehensive services, Taddiken Tree Company certified arborists bring a friendly and helpful attitude with excellent customer service. We’ll get to know you and your trees, so that giving your trees and plants the best care will also fit your priorities.

We take a holistic approach to tree care, whether the tree is a fruit tree, an ornamental feature, a stand-alone specimen, or part of a forest. From the soil under your toes to the air around your hair trees need us to remember and respect their natural habitat. So, for more than a decade, Taddiken Tree Company has led trees in the right direction, helping them grow strong to endure the harsh winds and storms we experience in Boulder, Denver, and along Colorado’s Front Range.

Team Bios

Aaron Taddiken
Founder & CEO
Aaron started in arboriculture (the study of trees) as a young man who daydreamed about climbing trees for a living. He followed that passion through mastery of his climbing skills, into furniture making and back into the urban forest.
Aaron has created two software programs for managing various aspects of the urban forest and its trees.
He created TreeHub after wanting a way to visualize and track many redundant processes in the operation of the business. We use TreeHub to manage many parts of the business from mapping client trees on their properties to creating proposals, schedules and invoices.
The most recent application is a tool designed to help urban mills manage their lumber inventories and track the stories from source tree to finished products.
