About Us

Developmental Behavioral Center

Our Story

The professionals at Children’s Hospital’s Developmental Behavioral Center have chosen to work with children whose struggles at home and in school offer challenges. They provide diagnostic information and treatment that is based on years of experience and knowledge of child and adolescent behavior.

When providing care, they believe it is important to consider all aspects of a child’s development. For this reason, they evaluate children from a developmental and a functional  perspective to obtain an accurate and complete assessment of your child before they discuss treatment.

Space for the virtual visit:

It is important to find a quiet, private place for the visit to occur. The room needs to have good lighting and a place for your child to lay down, if needed, for the exam. Please make sure all pets are put away. Turn phones on silent.

At the time of the visit:

  • Make sure your child is with you. If your child is not present, the visit will be rescheduled.
  • Make sure your audio is not muted and your volume is turned up on your device.

  • No eating or smoking during the visit.
  • The parent/guardian does not have to be in the same location as the child for the visit. Parents can join the zoom call from another location.
  • If the patient is a teenager, ensure there is an area where they can speak privately with the provider if needed
