Pediatric Allergy and Immunology
Ronit Herzog

Asthma is not a "one disease fits all. Our goal is to evaluate every child that has recurrent respiratory symptoms for an underlying allergies and aberration in the immune function. Hence, we are hoping to shorten the time for diagnosis of immune deficiency, which currently stands at the national mean of several years.
