Dr. von Stietz utilizes Cognitive Behavioral Therapy (CBT), Exposure Therapy, and Mindfulness-based approaches to treat mood and anxiety issues such as social anxiety, panic attacks, agoraphobia, post concussion syndrome, depression, hoarding, and insomnia. He also uses Exposure and Response Prevention (ERP) to treat OCD and it’s various subtypes (e.g. contamination, harm, sex, somatic, and pure-o). He frequently adapts evidence-based CBT approaches to fit the cultural needs of individuals such as those from LGBTQ, collectivistic, or underserved communities. Often times, individuals wish to make changes in their lives but fear unexpected negative consequences. At these times, Dr. von Stietz utilizes Motivational Interviewing to help individuals manage their ambivalence, overcome barriers, and take steps toward achieving their goals.
