Our Food Allergy Program

Our practice has a special interest and expertise in food allergy. For children with anaphylactic food allergies, we offer an active oral immunotherapy (OIT) program as an alternative to simple allergen avoidance.

“Dr. Ho is amazing!! He takes the time to fully understand what is going on and figure out what is the best course of treatment. I would 110% recommend him to anyone.”

“Dr. Guirguis has helped me control my allergies and asthma for many years. Even after I moved to South Jersey, I still travel over an hour for my monthly shots and office visits. She is kind, patient, and very knowledgeable… a great doc!!!”
