Our Team
Our ADHD & Autism psychologists are selected based on a number of qualities. Compassion and patience are essential qualities we look for in our psychologists. Since we focus only on Autism and ADHD, our psychologists are very knowledgeable about neurodiversity and understand the nuances of how Autism and ADHD appear in different populations (specifically in women, BIPOC, and non-binary adults).
Many other clinics use social workers to do your testing. Social workers or LCSWs make excellent therapists, but they don't have the in-depth training that comes with being a diagnostician or psychologist. Our team has spent years learning how to diagnose different mental health challenges, including Autism and ADHD.
