About Us

The Eating Disorders Care and Assessment Team is a multidisciplinary group of clinicians from both the Counseling Center and Health Services. Having an interdisciplinary team allows us to support different aspects of a students’ recovery from their eating disorders. Our team meets weekly to discuss students’ treatment progress, and to ensure continuity of care. The Eating Disorders Care and Assessment Team often collaborates with other campus partners, as well as with mental health and medical professionals in Waco.
