About

In her clinical role as a licensed psychologist, she provides individual therapy and career counseling. She focuses on working with diverse populations and has an expertise in working with individuals who struggle with anxiety, career challenges, and adjustment to parenting.
Dr. Karthaus has a great deal of experience helping clients find value and meaning in their careers. She offers both formal career-counseling sessions and integrates career counseling and individual psychotherapy sessions as it is relevant to clients’ needs.
Approach to therapy
As a behavioral therapist, Dr. Karthaus aims to help clients identify patterns of behavior and make active choices to move towards their values. She believes that much of the pain in life stems from avoidance. While avoidance of pain is a universal human experience, it often leads to moving away from values in an effort to feel less intensity.
With this in mind, her approach to therapy involves (a) working with clients to understand the function of their behaviors (b) increase mindfulness skills and expand emotional awareness and (c) increase willingness to make the changes that would help them move towards a more valued life.
