Dr. Zadeh is a wonderful doctor. I have had sinus problems for a while and wanted to get it under control. I went to other doctors, but didn't feel comfortable with any of them. I appreciated Dr. Zadeh's non-surgical approach to my treatment. In addition, he is one of the few doctors in the the LA area that can perform balloon sinuplasty in his office. I am very glad to have found Dr. Zadeh. He truly has improved my sinus problems.
