Certifications & licenses
Who certifies our arborists, and the state licenses our applicators hold to treat your trees.
ISA Certified Arborists
Certified through the International Society of Arboriculture, with an ISA Professional Membership. An ISA Certified Arborist has passed an exam on tree biology, pruning, diagnosis and safe work practices, and keeps the credential current with continuing education.
Colorado Department of Agriculture
Our applicators hold Qualified Supervisor licenses from the Colorado Department of Agriculture. A Qualified Supervisor is the license that lets a person direct pesticide applications; a Certified Operator applies under one. It is what allows us to treat emerald ash borer, Dutch elm disease, iron chlorosis and the other problems Denver trees run into. Each person's QS number is on their card on our team page.

Colorado Certified Nursery Professional
Our office manager holds the CCNP from the Colorado Nursery & Greenhouse Association: 2,000 hours of industry experience plus exams on plant health, pests, disease, pruning, turf and weed control, renewed every three years with continuing education. It is an industry certification rather than a state licence, and CNGA publishes no directory of holders, so ask us and we will show you the certificate.
Fully licensed & insured
Licensed and insured for tree work on residential, HOA and commercial property. Ask for our certificate of insurance before any crew starts work — on our jobs or anyone else's.
Safety standards
The standards our crews work to, and the award that recognized them for it.
Pinnacol Circle of Safety Award, 2019
One of just 50 Pinnacol Assurance customers recognized for workplace safety, including training, equipment maintenance and risk control.
OSHA & ANSI Z133 standards
Our crews follow OSHA requirements and the ANSI Z133 safety standard for tree work: the rules covering climbing, rigging, chainsaw use, aerial lifts and electrical hazards.
In the community
Locally owned since 1995, and the volunteer work we turn up for.
Saluting Branches
We volunteer early-fall tree care at veterans' cemeteries with Saluting Branches, the arborist-founded day of service honoring U.S. veterans.
Locally owned since 1995
Paul Smith founded American Arbor Care in 1995. It is still family operated, with 20+ team members serving Denver-area homes, HOAs and businesses.
