Hi - Do you have a list of certified arborists? I did search the site and wasn't able to find it. Thank you.

Extension doesn't collect that information or maintain a database of individuals or companies, but we can share the accrediting organization's (the International Society of Arboriculture) online search tool for certified arborists. You can also look for a Maryland licensed tree expert, who should have the same level of training and expertise as entry-level certified arborists even if they don't hold an official ISA certificate. (The ISA also has more advanced certifications, like Master Arborist and TRAQ - tree risk assessment qualification, for evaluating hazard trees.)
