Our mission is to provide the highest quality health care in a fun and comfortable environment. Let Irving Pediatrics be your child’s new medical home. A medical home is the one place you take your child for all their health care needs. You child’s medical home offers the best care because the staff knows you, your child and your child’s health history.

We believe that every child should have a medical home where their care is coordinated across the full healthcare system. This means that we help you access and coordinate care between hospitals, specialists, pharmacies, schools and other community based healthcare professionals.
