2. Become a Certified Arborist (It’s Mandatory!)
Before you can assess risk, you need a baseline understanding of tree biology, soil science, and urban forestry. Becoming an ISA Certified Arborist is the industry standard and typically the first step.
Here’s how to qualify:
-
Experience: 3+ years of full-time, practical work experience in arboriculture.
-
Exam: Pass the ISA Certified Arborist exam, which covers topics like pruning, diagnosis, tree biology, and safety.
📘 Explore the certification process at the International Society of Arboriculture (ISA)
3. Advance to Tree Risk Assessment Qualification (TRAQ)
TRAQ is a specialized credential offered by ISA that focuses specifically on evaluating tree risk.
To qualify, you must:
-
Be an ISA Certified Arborist, BCMA, or equivalent.
-
Attend a TRAQ course and pass both the written and performance-based assessments.
The TRAQ credential sets you apart, signaling to clients and insurance carriers that you are fully qualified to assess and manage tree risk.

Like any serious business, your Tree Risk Assessment company needs a strong business plan.
Start by defining your target audience. Will you serve:
-
Residential property owners?
-
Commercial developers?
-
Municipalities?
-
Legal and insurance professionals?
Then, define your value proposition. What makes you unique? For example:
-
“We specialize in legal expert witness testimony for tree failure claims.”
-
“Our firm uses drone inspections and tomography for advanced assessments.”
-
“We offer same-day risk evaluations for storm-damaged properties.”
Your business plan should also outline:

5. Legal Setup: Form Your Company and Get Insured

Workers’ compensation (if hiring)

Commercial auto (if using a work truck)
📎 Pro Tip: Use NEXT Insurance or Hiscox to quickly compare coverage for arborists and consultants.
6. Invest in Tools and Technology
You don’t need a bucket truck or chainsaw for this line of work — but you do need specialized tools.
Essentials include:
-
Resistograph or tomography tools for decay detection

Binoculars and pole cameras

Drones (if licensed by FAA)
-
Tablets or laptops with GPS/mapping software

7. Build a Library of Tree Knowledge
To be seen as an authority, you must become a lifelong learner. Here are must-read resources:
The more you read and study, the better your field reports and recommendations will be — and the more likely you’ll get referrals from attorneys, city planners, and landscape architects.
