Welcome! I specialize in working with children, teens, and adults who are experiencing emotional challenges and behavioral difficulties. I also work with parents at any stage of parenthood, including pregnancy and postpartum periods, to help parents and children work through difficult feelings and challenging situations. I enjoy taking a positive and compassionate approach to helping all of my clients. I use humor, compassion and empathy in order to build connection with my clients and support them in working towards their goals.
I use Cognitive Behavior Therapy and Rational Emotive Behavior Therapy techniques, in addition to parent management training tools. I often work to help children through feelings of anxiety, depression, and anger while supporting parents as children are managing difficult feelings.
If you or your child are going through a rough time emotionally or if you are struggling with how to best help your child, please contact me. We can speak by phone before meeting to explore whether we are a good fit and how I may be able to help.
