We will have a panel of experts, including Andy Trotter (of West Coast Arborists, Inc.) and SCA Board Vice President Chris Ahlum (of Ahlum & Arbor Tree Preservation) discussing why they've chosen to certify, and how it has helped them and their crews in regards to plant healthcare and business practices.
