Practicing our Promise winnerAt Cook Children's, taking care of kids means including the whole family. We take the time to listen to you and your child, answer questions and help you navigate the "perils" of parenthood.

We're parents too! We know kids when they're at their best ... and when they're feeling their worst. Our pediatricians are specialists in the health care of infants, children and adolescents.

We're here to help you with well-child visits, vaccines, illnesses, behavior problems, learning disorders, and to answer questions all parents have at one time or another. If your child has a chronic illness, we're here to provide you with a medical home and make sure he or she gets the attention and care they need.

Together with you, we'll get your kids on the path to leading happy and healthy lives!
