My Ideal Client

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. This may include struggles with obsessions and compulsions, intrusive thoughts, worries, panic attacks or physical symptoms of anxiety. I work with adults, teens and children by providing specific tools and strategies to empower them to take control of anxiety.

My Approach to Helping

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 Personal Beliefs and Interests

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 6 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.

Techniques I Use


  • Exposure and Response Prevention Therapy External link

    ERP is the gold standard for treating OCD and other anxiety disorders. It is evidence based and highly effective. This is a behavioral intervention that we will work together to implement. I believe it is important to teach my clients as much as possible about these treatment approaches so that there is a thorough understanding of how they work and why they work!

  • Cognitive Behavioral (CBT) External link

    CBT views our behavior as fundamentally influenced by our thoughts and emotions. CBT allows us to better understand these maladaptive or 'dysfunctional' thoughts and replace them with those that have a more positive influence over our behaviors. While we certainly cannot control everything and everyone around us, our thoughts and feelings are aspects of our lives that we can gain control over.

Issues I Treat


  • Child or Adolescent Issues External link

    Prior to beginning private practice, I worked as a Child and Family Therapist in an intensive outpatient setting for Trillium Family Services which is Oregon's largest provider of mental and behavioral healthcare for children and families.

  • Anxiety External link

    My private practice has focused on helping adults find the tools and the strength to manage the often overwhelming stress and anxiety that comes from the busy and demanding lives that we lead as well as anxiety that may be the result of loss, life transitions or stressful relationships.
