About Wilfredo Y. Alejo

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 (909) 860-1144.
