Hello and Welcome to My Practice!

My name is Donald S. Levy M.D.and I have been practicing medicine in the city of Orange (Orange County), California since 1988. I specialize in treating patients with allergic diseases such as asthma, hay fever, hives, eczema, insect stings, drug allergy, food allergy, eosinophilic esophagitis, anaphylaxis, and angioedema. I have a special interest in patients with Hereditary Angioedema and have done clinical trials and co-authored journal articles on this disease state. I also have given lectures in The United States and Europe on my research results.

Care Philosophy

In my practice, caring for patients is our primary concern, and we pride ourselves in providing compassionate and friendly care. I strive every day to keep learning and growing my knowledge base to provide you, my patient, with personalized, caring, state of the art medical treatment of your allergic diseases. We want to be your partner in health. We treat our patients as if they are our own family members.
