Our mission is to preserve and restore trees throughout the Roaring Fork Valley and beyond



Trees have the highest value of any landscape asset, but they are often overlooked in maintenance budgets. Pruning and natural care will insure they thrive for years to come.



Organically based, high quality products improve the health of the soil and result in a stronger, greener and more drought tolerant lawn that does not compete with your other landscape plants.


Aspen Tree Service is a locally owned and operated, full service tree care company with a highly educated and experienced team of professional arborists who are committed to the highest standards of care.

You can rest assured that the work we recommend and perform is what’s best for your trees. Your landscape is a highly valuable asset to your property, you should be sure that it’s being cared for as such.

Aspen Tree Service has been accredited in accordance with Tree Care Company Accreditation standards put forth by the Tree Care Industry Association (TCIA), America’s oldest and most respected tree care trade association. Accredited tree care companies must re-apply every three years so that their practices can be reviewed and the continuation of best business practices can be verified.
