What you can expect

Your child’s first session with a DHIM provider is generally attended by the patient and his/her parents or caregivers; this participation is a critical first step in the treatment process.  For two-parent families, both parents are highly encouraged to attend, and treatment consent is needed from each parent.

DHIM providers work together with the child and parents/caregivers to discuss concerns and goals, and develop a diagnosis and treatment plan that is manageable for all involved. Treatment plans may include recommendations for psychotherapy, medication, and, if necessary, hospitalization or a referral for additional care.

After the first appointment, we may request permission to contact your child’s therapist, school, or primary care provider (PCP).

DHIM does not provide comprehensive, “wrap-around” services for patients with disabilities related to severe mental illness, substance use disorders or eating disorders nor do we provide disability or forensic assessments.
