Gillian Sleeman

Licensed Marriage Family Therapist

We have all certainly experienced anxiety at some point in our lives, but if it is persistent and if it begins to interfere with your day to day life, you may have an anxiety disorder. My specialty is the treatment of anxiety disorders and OCD, and I look forward to working with you to find relief.

My Approach

Cognitive Behavioral Therapy (CBT) and a the more specialized approach of Exposure and Response Prevention have been shown repeatedly to be the most effective treatment interventions for anxiety and related disorders, including OCD. While this is the primary therapeutic orientation used in my practice, I also believe that the relationship between therapist and client is very important in determining therapeutic outcomes. I consider my approach to be open and collaborative and we will work together to identify both long term and shorter term (week to week) goals to help you track your progress and feel that you are making important and lasting changes to your mental health.

My Background

I graduated from Lewis and Clark College with a degree in Marriage, Couple and Family Therapy. My experience prior to private practice included work in outpatient and residential mental health settings, working with children and adults on issues ranging from addiction to depression to childhood behavioral challenges. I have spent the last 3 years obtaining specialized training in the areas of anxiety and OCD and the use of CBT and ERP as treatment modalities, including completing certification at the Behavioral Therapy Training Institute. I am passionate about this specialty and the power of treatment and consider it a privilege to work along side my clients as they learn about these tools and use them to improve their quality of life.
