Questions & Answers

A: We treat Urgent Care patients from birth to age 26.  If we are very busy, we give younger children priority and may ask the young adult to be seen in Adult Urgent Care.

A: You should come to After Hour Pediatrics if your child requires urgent care when your pediatrician or primary care physician’s office is closed.  We are a convenient and affordable alternative to the Emergency Room.  If the injury or illness is life-threatening, you should go to the nearest hospital.

We are open 365 days a year, Monday-Friday 5pm -10pm and Weekends/Holidays 10am-10pm.

If you are in doubt about whether to come and visit us please call us at 650-579-6581

A: The typical visit requires 30 -60 minutes depending on the services you need.  If you need lab tests, breathing treatments or a procedure performed, you may be in the office for longer.  During surge of illnesses or patients with emergencies, wait times can be longer.

For Urgent Care,  you can “Save a Spot” or drop in.  We see walk in patients in the order that they arrive with exceptions for critically ill children or those at high-risk.  We do our best to see “Saved Spots” on time, and always leave openings for walk in patients.

  • We believe sick or injured children should be seen by a pediatrician.  Other urgent care facilities may have pediatric rooms or areas designated for children, but they are not staffed with clinicians who have specialized training in pediatrics.
  • We are ideally located in downtown San Mateo, 10 minutes from San Francisco airport.
  • We offer free parking right outside our front door.
  • We are child friendly, caring, compassionate and gentle.
  • We will work with your child’s primary physician, informing them about your visit and ensuring they are fully briefed about your child’s medical situation as soon as possible.
  • We are independently run so you can talk to us about financial pressures.  We might be able to help.
