Treatments Offered

Eating Disorders

Eating Disorders are complex and can cause significant impact on psychological, physical, medical, and cognitive aspects of the individual's life. Dr. Corona specializes in providing Family Based Treatment (FBT) for Eating Disorders and Cognitive-Behavioral Therapy (CBT) for Eating Disorders, in order to help get individuals back to their normal life. FBT is a treatment approach that has strong scientific support in treating adolescents with eating disorders, and uses parents/caregivers as a primary source in recovery. CBT focuses primarily on thoughts and cognitions that are contributing to the eating problems. If warranted, Adolescent-Focused Psychotherapy for Eating Disorders is also provided.

Diagnoses treated include: 

Anorexia Nervosa, Bulimia Nervosa, Binge-Eating Disorder, Other Specified Eating Disorder, and Avoidant and Restrictive Food Intake Disorder

Anxiety & Depressive Disorders

Depression, fear, and anxiety are some of the most common and uncomfortable emotions that we can experience at some point in our lives. Children and adolescents can also experience anxiety and depression. Cognitive-Behavioral Therapy (CBT) for Depression, and Cognitive-Behavioral Therapy (CBT) for Anxiety are evidence-based treatment for these conditions. Exposure Therapies, and Behavior Therapy, may also be applied as needed. 

        Diagnoses treated include: 

     Generalized Anxiety Disorder, Social Anxiety, Specific Phobias, Obsessive-Compulsive Disorder, and Major Depressive Disorder. 

Additional Disorders & Therapies

Dr. Corona can also provide psychotherapy treatment for other child and adolescent concerns including parent training for behavioral problems, stress management, adjustment problems, social stressors, and chronic abdominal pain.

Dr. Corona is happy to provide an initial 10-15 minute consultation call to discuss your case and determine if she is good fit for your treatment needs.
