Arborist Consultation in the San Francisco Bay Area
Comprehensive Tree Evaluations, Risk Reports, and Expert Recommendations from a Registered Consulting Arborist
Professional Tree Consulting • Reports • Expert Analysis
At Arborist Now, we provide professional arborist consultation services throughout the San Francisco Bay Area,
led by a Registered Consulting Arborist (ASCA).
Unlike a complimentary estimate or quick site visit, an arborist consultation is a stand-alone professional service. It delivers an impartial, science-based evaluation of your trees, supported by detailed reporting, expert recommendations, and decades of local field experience.
Our consulting division works with homeowners, developers, architects, contractors, attorneys, and municipalities, offering trusted expertise on every aspect of tree health, safety, and preservation.
What Is an Arborist Consultation?
A professional arborist consultation involves a comprehensive on-site evaluation by a certified expert trained to identify potential risks, diagnose health issues, assess structural stability, and provide objective written reports.
Whether you’re planning construction near mature trees, facing a tree-related dispute, or seeking city permit compliance, our consulting arborist brings the insight and documentation needed to make informed, defensible decisions.
