William E. Berger, M.D., FAAAAI, FACAAI

“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.”

 

What's New

Allergy and Asthma Associates has established the Food Allergy Center, the first and only one of its kind in Orange County, to focus exclusively on the diagnosis and now treatment of food allergy. We are now offering oral immunotherapy. The purpose of oral immunotherapy (OIT) is to decrease your sensitivity to allergy-causing foods, so that exposure to the offending food (peanut, milk, egg, tree nuts etc.) will result in fewer and less severe symptoms in the event of an accidental exposure.

What Our Patients Say About Us

  • I couldn’t breathe, I couldn’t do anything that I wanted to do, let alone go out and do anything athletic with my children or for myself. Then I met Dr Berger. He changed my life – he put in the time, the effort and the extra research to get me the diagnosis and the correct medications that changed my life forever!... - Linda

  • When I first got diagnosed with asthma it started off as exercised induced but throughout the years it became worse than that. Just a wind would make me feel like I needed to take my inhaler, a change in the weather and I had to take a breathing treatment. It was really hard especially for being an athlete, because you don’t want anything holding you back from what you love to do...
