A UCLA Professor, several degrees & awards from several associations & organizations (including Invisalign) and universities such as UCLA, NYU, extremely kind & friendly, intelligent and knows what he is doing. I had my braces for 1 year, and a bionator (retainer) for 2 years and my teeth came out great! His assistants are very kind and helpful, and Dr. Dayani is a person who you can have a regular conversation with and has a good sense of humor combined with extremely good knowledge of his practices which allows his treatments to be painless, relaxing, stress less and the end results are great. The cost is probably around the average doctors fees for the treatment and visits, but it worth it. Overall, Doctor Dayani is a extraordinary orthodontist with many patients of all types, each with different oral conditions, he is able to treat them all!
