She is dedicated to being a stable base from which her clients are empowered to apply their strengths to the challenges in their lives, find meaning and direction, and be their most effective.

Ashlen works with a range of presentations including depression, low self-esteem, grief and loss, stress, adjustment and life transition difficulties, issues with identity, and complex trauma. Her special areas of interest are in the treatment of anxiety disorders, the obsessive and compulsive disorders, and relational attachment issues.
