Amelia Ladd, M.S.

Amelia Ladd, M.S., is a student therapist at the Anxiety and Panic Treatment Center. She is about to begin her fourth year of doctoral training in clinical psychology at Pacific University School of Graduate Psychology and is being supervised by Robert W. McLellarn, Ph.D., to ensure that you are getting the best care possible. Her approach to treatment comes from a cognitive behavioral therapy (CBT) perspective, which suggests that thoughts, behaviors, and emotions are all interrelated, and change in one domain will cause change in the other two domains. CBT focuses on reducing unwanted symptoms, usually by targeting thoughts and behaviors as the mechanisms for change. She also integrates interventions from acceptance and commitment therapy (ACT), which focuses on one’s willingness to experience uncomfortable feelings in order to engage in value-driven behavior to live a more fulfilling and values-congruent life. The interventions used depend on the preferences and symptoms of each individual client. Her first goal as a therapist is to collaboratively form a trusting and respectful relationship with each client. To do this, she believes it is essential to honor the diversity found within each client, which means taking the time to understand and incorporate cultural factors into treatment. In addition, she has experience with hoarding disorder and will make home visits if deemed necessary.
