Tools like the IOCDF’s provider locator or the American Psychological Association (APA) psychologist locator can help you narrow down reliable professionals who specialize in treating OCD. If you are looking for online therapy, you can also narrow down your options using these tools.
Every professional on the IOCDF site has experience in ERP. On other sites like the APA's, you may have to ask about their professional experience.
NOCD has a site as well as a mobile application with many resources for overcoming OCD.
If your insurance covers part of or all ERP costs, check your provider’s directory for specialists or ask whether it covers out-of-network experts.
Ultimately, the goal is to find a professional you feel comfortable with and one who meets your needs. It's important to take the time you need during your (typically free) consultation to ask any questions that may put you at ease.
