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
  • Unselfish – 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.
