Does your child or adolescent’s behavior leave you wondering, “What is going on?”Are they having meltdowns, withdrawing, struggling at school, worrying, or feeling sad? Children and adolescents often communicate their feelings through behavior long before they have the words to explain what they are experiencing.I work with children, adolescents, and families navigating challenges such as adoption, divorce, co-parenting, blended-family transitions, grief and loss, school-related worries, family conflict, and the growing push for independence. I help children and caregivers better understand what may be underneath the behavior while strengthening connection, communication, and emotional regulation.
