We saw Dr. Hanissian for a 2nd opinion after my son had a reaction to shrimp at the beach. Our first appt with a different doctor showed an allergy to tuna and apple and gave me little to no info on what to do nor how to use the Auvi-Q injector. Frustrated I searched and asked a friend for a recommendation for a second opinion. She suggested Dr. Hanissian and he was AWESOME!! He realized my son was tested too early after eating the shrimp and his antibodies would have blocked the test results. I went to get fresh shrimp for him to eat in office and he tested him again with skin pricks and found allergies to ALL shellfish!!!! I am so glad I went to see him!! He gave me so much information and took time to explain things to me carefully and patiently. I cannot say enough good things about him and his staff!!!
