Dr. Chattha offers individual therapy using a cognitive-behavioural framework. This type of therapy is collaborative in nature and is skills-based. Dr. Chattha also has training in other forms of therapy (e.g., interpersonal psychotherapy, integrity-based) and is able to flexibly incorporate other approaches (such as Dialectical Behaviour Therapy, emotion-focused) depending on the nature of the presenting difficulties experienced by the patient. Therapy with adolescents may or may not involve other family members to support therapeutic efforts. Of course, any effective therapy is first rooted in developing a safe and comfortable therapeutic environment. Dr. Chattha strives to provide this for all of her patients.
