In Denver arborists need to be licensed but in some cities and counties in Colorado they don’t. That means it’s really up to you to find out if a Denver arborist is qualified and what sort of certifications they possess.
The state of Colorado doesn’t require a specific arborist license.
ArborScape is licensed in all five metro area cities that require a written and practical test: Aurora, Denver, Lakewood, Englewood and Wheat Ridge. Arbor Scape also meets or exceeds all insurance requirements for the State of Colorado, local municipalities, Colorado Department of Motor Vehicles, homeowners associations, and workmen’s compensation.
We also are ISA certified by the Rocky Mountain ISA.
