- National Board-Certified Counselor, 2014
I have been a school counselor since 2002. I’ve worked at the primary and secondary level focusing on cognitive behavioral therapy and solution-focused brief therapy. I believe if one changes the way they think they will change the way they feel.
Prior to becoming a school counselor, I worked as a mental health therapist dealing with children and adults in crisis as well as providing brief and intermediate therapy.
I believe that dealing with the “whole child” creates a path facilitating the best outcome for the student in their educational pursuit. I am a firm believer in Social-Emotional Learning and believe that the lives of children will be better the more empathic they are.
My husband I love to travel – we have been all around the world and plan to continue to do this. I am an avid runner – I just ran my 12th marathon. I am so excited to become a part of the TAS community. I am ready to make a difference.
