Hi Rebecca, thanks for your question about finding an arborist you can trust. We recommend you go through the following website for ISA certified arborists. You can call the company and tell them your concerns and ask who specializes in that area. It is also good to get several opinions about your trees as they should come out and look for free and only charge if they do something.
