I am now a clinician with over 25 years experience in the world of mental health, trying to help people simply feel better as all of us journey through life. I have been specifically trained in DBT (Dialectical Behavior Therapy), EMDR (Eye Movement Desensitization Reprocessing Therapy) and TF-CBT (Trauma-Focused Cognitive Behavior Therapy). I sincerely enjoy connecting and working with people in order to find solutions to issues, relationships, or situations that are life-interfering. Outside of work one can find me busy being a wife as well as a mother of two children and 2 Brittany spaniels, who enjoys spending time with friends as well as hiking in the woods, cooking, reading, singing when I can and spending as much time as possible at the family cabin. Come chat with me.
