Dr. William E. Berger opened the practice in 1980 with the goal of providing exceptional allergy and asthma care; today he is partnered by Dr. Warner W. Carr, Dr. Mark S. Sugar, Dr. Simi Kapoor, Dr.Christina Schwindt and our certified physician assistant, April N. Showalter, each of whom shares this practice philosophy. We’ve helped thousands of children and adults find welcome relief from allergies, asthma, sinus problems, chronic cough and other related conditions. It’s one reason why half of our new patients are referred to us by our existing ones.

Next, our doctors have established themselves as leaders in the field of allergy and asthma. Through our Southern California Research Center, they have been involved in leading-edge research, clinical trials and testing for some of the largest pharmaceutical companies in the world that will improve patient care for years to come. In addition, they’ve written practice parameters for allergy, asthma and immunology specialists in the US, lectured throughout the country and held prominent positions in professional medical organizations and at university medical schools.

Finally, our doctors and staff will treat you just like family. You will truly appreciate our friendly, unhurried and informative care. And the same goes for your child. We make children’s allergy testing visits a fun and positive experience... every step of the way.

It’s highly specialized care that can help you greatly improve your health and your quality of life, and it’s available right here in Mission Viejo, Irvine and San Clemente.
