    Biography

    Biography

    Dr. Mayfield knew as a young teenager that becoming a pediatrician was her dream. She was—and still is—fascinated by the enormous complexities of the human body, and she derives great satisfaction from applying her knowledge.

    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.

    I like our physician very much. It might be helpful to give us some details on the near future items that might not pertain to right now. Like what we will need to do in our next checkup and a reminder for things like flu shots?

    I would like to receive emails telling me preventative care/check ups/tests for my son by age, shots.
