"Medicines and monitoring techniques have come a long way in the past few decades. Today, most asthmatics can live full and very active lives. Helping each patient learn to recognize their individual asthma or allergy triggers is key to treating, and even more important, preventing, future attacks. Empowering them through education and observation is one of the most exciting aspects of my work. Seeing them succeed in leading normal lives is the most rewarding."
