I was with a condescending awful allergist for years. Finally made the switch. So happy I did. Ricky took good care of educating me and gave me options and recommended tests. So happy to have someone listen and offer choices.
Great office and staff! Dr. Wong was very thorough and explained everything perfectly! He took his time and was very pleasant!
Dr Wong always listens, asks the right questions, and then figure out what caused my allergy and what treatment should be used to cure it. Thank you so much!

Ready to See an Allergist?
If you suspect you or your child may have an allergy, an evaluation with a board-certified allergist can help provide answers before you make major changes to your diet, lifestyle, or environment. By reviewing your symptoms and medical history and using targeted allergy testing when appropriate, an allergist can help determine whether a suspected allergen is actually causing your symptoms—and help you avoid unnecessary restrictions based on assumptions or unvalidated testing.
For suspected food allergies, evaluation typically includes a detailed reaction history and targeted food allergy testing. When appropriate, a supervised oral food challenge may be recommended to help confirm or rule out a food allergy.
If a food allergy is diagnosed, your allergist can create an individualized management plan that may include allergen avoidance, prescribed epinephrine, an emergency action plan, and discussion of available food allergy treatment options. While no evaluation or treatment can eliminate all risk, the right diagnosis can help you better understand and manage your allergies with confidence.
