  • Biography



    There’s a lot of joy in working with children, so pediatrics was an easy choice for me. It is very rewarding to not only help a child feel better, but also help them establish attitudes and habits for a lifetime of health. I work hard to develop a relationship with the 16-and-under crowd, as well as with parents who tell me they appreciate my compassion and thoroughness. Taking the time to listen to parents’ concerns and answer all of their questions is an important part of my practice.

    As the mother of three young children, I can really relate to both kids and their parents.

    There is nothing more important to me than the health and safety of your children. As a strong advocate of vaccinations, I believe that ensuring the children who visit our office are fully vaccinated is the single most important thing I can do to keep your children and your community safe. If you choose not to fully vaccinate your child, another physician may be a better fit for your family. If you have questions or would like more information on vaccinations, call our office at (714) 577-6677.

    Again, we love *Dr. Wu! Sad to see "administration or procedure" changes that affect patient car! Examples: getting through to the actual nurses/doctor and billing! As well the time wasted... the phones are a joke right now! We've been coming for 9 years & this is the worst ever!
    We love *Dr. Lillian Wu. Always so patience, loving, and caring for our kids.
    Dr. Wu is excellent with her patients and families! We have had Dr. Wu as our pediatrician for 9 years now, and have moved away, but still make the drive because she is an excellent doctor. Samantha is her nurse who always gives our children their vaccines, she is absolutely the BEST! I always ask for Samantha if we are due for vaccines, and she is always efficient and accurate with everything! I know there are new employees, but no matter what we ask for Samantha! Dr. Wu and Samantha are absolutely amazing, and we are so appreciative to have met them all those years ago, truly a blessing.
    Dr. Wu is a wonderful doctor! We live out of town but make the drive because she is absolutely so good at being a pediatrician! She is always informative, kind and listens to any concerns we may have!
    Dr Wu is the best...truly takes her time and listens to questions and concerns parents have!
