At Downtown Psychological Services, we have designed a simple process for connecting you to the right therapist.  After you contact us by phone or email, we will schedule you for a free, 15-minute phone consultation to find out what brings you to therapy and to answer any questions you have about our practice.

Following that discussion, we will assign you the therapist who best fits your needs and preferences. We believe, first and foremost, that comfort with your therapist is of the utmost importance to a successful therapeutic relationship. In rare instances, you may feel the dynamic is not working for you after a few meetings.  If this arises, we will help you find another therapist in our practice or elsewhere.  Our main goal is to ensure the relationship is right for you so that you can connect with and open up to your therapist so you get the most out of the process.
