Qualifications you can verify

A consulting arborist should hold, at minimum, ISA Certified Arborist credentials, and ideally the ISA Board Certified Master Arborist credential, the highest the International Society of Arboriculture offers. For written tree risk work, the ISA Tree Risk Assessment Qualification (TRAQ) is the recognized standard. I hold both, along with the licenses and training below, so the recommendations in my reports rest on formal qualifications you can verify.

Looking for a certified arborist near you?

If you are in El Dorado, Sacramento, Placer or Amador County, I can help. Here is how the credentials stack up. ISA Certified Arborist is the baseline certification of the profession. ISA Board Certified Master Arborist is the level above it, and the ISA reports that fewer than two percent of Certified Arborists hold it.

Whoever you hire, ask for the certification number and look it up in the ISA directory before the visit. Mine is WE-14385B. I work from Placerville and cover the foothills and the Sacramento area, from Placerville and Folsom to Sacramento, Roseville and Rocklin. The full list is on the service areas page.
