Pediatric Allergy and Immunology Faculty

Allergy and immunology spans both Pediatrics and Internal Medicine, with two pediatric-based and three internal medicine-based faculty who are all certified by the American Board of Allergy and Immunology, clinically active, and firmly committed to clinical teaching. Volunteer faculty members in private practice also participate in our clinical and educational activities.

In 2015, four Division faculty were named Best Doctors in Dallas by D Magazine and two were listed in Texas Monthly Magazine as Texas Super Doctors. Additional honors and awards, as well as presentations and publications are highlighted in the 2015 annual report.
