    “I entered the field of medicine because I wanted to make a positive difference in the lives of others. I chose to specialize in allergy and immunology because allergies, asthma and other related conditions affect many millions of people of all ages in the US. Today, I offer my patients over 30 years of experience along with a commitment to exceptional patient care. I take the time to listen to my patients and explain their condition and any recommended treatment in simple, easy-to-understand terms.

    “Throughout my career, my commitment to improving patient care has extended beyond my practice. I've conducted clinical research on allergy and asthma medications for more than 50 pharmaceutical companies and have published in numerous books, journals and abstracts. Lastly, I am proud to have served as president and chairman for several professional medical organizations.”
