History

Established in 1980.

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 and our certified nurse practitioner, 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.

We serve the communities of Lake Forest, Mission Viejo, Newport Beach, Rancho Santa Margarita, San Clemente, San Juan Capistsrano, Talega, Aliso Viejo, Coto de Caza, Dana Point, Irvine, Ladera Ranch, Laguna Beach, Laguna Hills and Laguna Niguel in Orange County (OC), CA.
