Pediatric Services

At St. Joseph Heritage Medical Group, we are dedicated to offering the highest quality pediatric care. We love to partner with parents in caring for children—from tiny newborns to rambunctious teenagers. Serving the communities of Garden Grove, Orange, Santa Ana and Tustin, our pediatricians and many of our family physicians have expertise in assisting with problems and challenges that can arise while raising a family.


We offer same-day sick child appointments with your doctor as well as after hours Urgent Care services. If your child requires hospital care, our doctors are on staff at CHOC Children’s, Children's Hospital of Orange County.

We have pediatricians and family practitioners at our three office locations. Click here for a physician directory.
