Welcome to After Hour Pediatrics, we are a family-friendly children’s urgent care and minor emergency center in downtown San Mateo, 15 minutes south of San Francisco Airport.

For over 20 years, we have provided urgent medical care to babies, children and young adults from San Mateo, Burlingame, Millbrae, San Bruno, San Carlos, Belmont, Redwood City, and Foster City.  The clinic is easy to find, and has parking right outside the door.

Our clinic is open for Urgent Care after hours when your child’s doctor is often unavailable.  Just walk in!  You don’t need an appointment.

We have some of the best children’s doctors in the Bay Area and are a great alternative to the hospital emergency room, which can be traumatic and incur higher costs and longer wait times.

Most major health insurances are accepted.  Our billing office manages the entire process with your insurance company.

Our staff is kind, caring and dedicated.  We aim to bring a smile back to the faces of the 7,000 children who come through our doors each year!

With healing hands and caring hearts, we look forward to helping your child.


Quick, efficient, and very professional. This place is wonderful and I would recommend in a heartbeat!


I love After Hours Pediatric Urgent Care. With 5 children it’s comforting to have a place…where the doctors actually listen, and they always follow up….from stitches to asthma to strep and even flu. This is our first choice hands down.
