Patient Care

What to Expect:

When you are referred to the Developmental/Behavioral Pediatrics team, you will receive a packet of forms that will need to be completed and returned before your appointment will be scheduled. This information will help us identify who will be the most appropriate provider for you to see first.

At the first appointment (which will last approximately 1 hour), we will ask questions to get background information, review any records that you bring, and have you sign release forms to allow us to gather additional records from schools, physicians, or other providers you have seen in the past. We may also refer you for some additional medical testing or developmental services (e.g., speech/language evaluation) depending on your child’s unique needs.

From there, the Developmental/Behavioral team will determine whether additional evaluation is needed in our clinic. You may be referred to Dr. Hickey or one of the psychology interns or practicum students for further testing (up to 2 additional appointments). This may include testing of intellectual abilities, academic skills, executive functioning skills, social communication, or emotional functioning. If needed, we may schedule you to meet with Dr. Patterson for a summary and final recommendations.
