Welcome to the Allergy and Asthma Treatment Center, where our goal is to manage disease using the principles of prevention of disease, avoidance of illness triggers, and the management of each patient with a personalized treatment plan. I am a native of Los Angeles. I received my medical degree from the UCLA School of Medicine, then trained in the field of Internal Medicine and subsequently specialized in the field of Adult and Pediatric Allergy and Immunology. I chose to stay here for my medical training given that UCLA provides one of the best medical education programs in the country. I have taken care of patients in various hospitals in the L.A. area including UCLA, Cedars Sinai, Children’s Hospital Los Angeles, and The Greater Los Angeles Veteran’s hospital. As an allergy specialist, I believe that identifying and eliminating environmental factors is critical to the control of allergic disease. In addition, with allergy injections, I can help patients achieve tolerance to their allergic triggers so that they can live their lives free of allergy symptoms. Thank you for your interest in the Allergy and Asthma Treatment Center. We hope to see you in our treatment center soon.

- Marine Demirjian, M.D.
