“As a child I had allergies. I saw an allergist throughout my youth and really thrived after that. It made me feel that in the future I could do the same thing for people.

“Allergy and Immunology is a field where you can actually cure people. You can watch them go from being really sick to becoming very healthy. It’s truly gratifying to hear from a patient that you’ve made a difference in their life.”
