Clinical Work

Dr. Williams administers expert psychological treatment for several mental health conditions, including a specialized treatment for OCD, called Exposure and Ritual Prevention (EX/RP).

Dr. Williams also offers comprehensive evaluations for psychological disorders, treatment for health anxiety, phobias, trauma, and body dysmorphic disorder. She is a leading expert in race-based stress and trauma. She also provides therapy for people seeking to improve the quality of their relationships using Functional Analytic Psychotherapy (FAP).
