The pediatricians at Monarch Pediatrics welcome you to our kid-friendly office, conveniently located at I-270 and Olive Boulevard. We schedule same-day appointments for well and sick visits. We also have walk-in clinics on weekdays for our existing patients. It is also that time of year for nurse-only visits for seasonal influenza and COVID vaccines for patients 6 months and up, as well as RSV antibodies for our babies less than 8 months of age.

Thanks for helping us support families fighting pediatric cancer! #toydrive #pediatriccancerawareness #holidaygiving #thebennettproject #monarchpeds #stlpeds #takingcareoftinyhumans Our office is closing a little early today (4pm) to allow all of our staff plenty of time to vote! Have you made sure your voice has been heard?!? Super excited to announce that Monarch Pediatrics won the door decorating contest for our building for Halloween! Happy Halloween from all the butterflies and lepidopterists of Monarch Pediatrics. We hope you have a safe and healthy holiday. And let the kids eat a little candy today. 😉 Are you wondering if your child is staying on track with his/her development? The CDC has an excellent milestone tracker to help you find the answer! And you will find that we screen development at office visits based on these listed milestones. We also have the link on our office website.
