On this episode of Smile Politely Radio, we are joined by Sharon Lilly from the International Society of Arboriculture. ISA is a professional organization promoting urban tree care worldwide and its headquarters is in west Champaign. We discuss what exactly an arborist does, how to find the right arborist, and why exactly ISA is located in the middle of Central Illinois. Plus, we talk about proper tree care for the nonprofessionals and all the great benefits we get from urban trees, including our mental health.
