Looking for a Pediatrician in St. Charles County or Wentzville? Our Cottleville team is here to care for your child – and not only when they’re not feeling well. We help keep them healthy throughout their childhood, too.
In our pediatric practice, you’ll find an environment of healing, compassion and support. We use the latest treatments and technologies, including the online tool MyMercy, so you can take an active role in your own health.
Your child's health history is stored in their electronic health record. So anytime you visit another Mercy facility – for tests, emergency care or specialized treatment – your child's health information is right there with them.
And as part of Mercy Clinic, we can connect your child to specialists anywhere you find Mercy and work together to deliver care that’s built around you.
For non-emergency assistance after hours, call our exchange at (314) 364-5277.
