DID YOU KNOW…
All of our physicians are Board Certified in Pediatrics.
All children should be examined at least once yearly throughout their lives. Although children are usually very healthy, an ounce of preventative medicine (including vaccinations) can help keep your child healthy for years to come.
We consider it our privilege to care for your children from birth through age 21.
For the safety of our children, we require a note of authorization from you if someone else will be bringing your child in to be seen. Please ask a staff member how a notarized form can eliminate the need for these notes for an entire year.
Our on-call physicians can be reached throughout the day though by calling 363-3000. Please reserve after-hours calls for URGENT and EMERGENCY calls only. Calls regarding dosage or refill of medications should be made during regular office hours or to our non-emergency nurse line at 214-0900.
The following symptoms are considered emergent in newborn babies that are less than two months old: - Fever greater than 100.4 F (Take baby’s temperature rectally if baby feels warm and temperature is normal under the arm).
