Dr. Karthaus is a founding partner and the Business Manager for Aviva Psychology Services. Dr. Karthaus is a visionary and a phenomenal systems thinker. She is gifted at translating ideas into action, and at implementing efficient systems to optimize organizational functioning.

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.

In practice, Dr. Karthaus works from a mindfulness-based perspective, integrating evidence-based interventions from Acceptance and Commitment Therapy (ACT) and Cognitive Behavioral Therapy (CBT). She is a registered yoga teacher, which informs her work in helping clients to cultivate intuitive strategies for managing the stress of daily life. Finally, as a counseling psychologist, Dr. Karthaus has a great deal of experience in helping clients find value and meaning in their careers. She offers both formal career-counseling sessions as well as integrates career counseling into individual psychotherapy sessions as it is relevant to clients’ needs.

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.
