Allergist and Immunologist
I have always been fascinated by the immune system. Because allergy is a disorder of the immune system, I naturally gravitated to this field of medicine. I have always enjoyed helping people understand allergies and how best to treat them.
A Little About Me: I grew up in New Orleans and also completed my undergrad and medical school education there. My family would often travel to the southwest when I was young, so early on in life I developed an affinity for Arizona. I decided to move to Phoenix in 2009 to start my career and was eventually elected president of the Arizona Allergy & Asthma Society by my peers. I moved to Texas for a few years to help take care of my parents in their later years but I am excited to be back in the valley as an allergist at Premier Allergy, Asthma and Immunology.
