The staff act in a professional manner and are very amiable, Dr. Nawaf Masri is not. He is an extremely condescending and smug individual who even stoops to belittling his patients at times. But you will need to carry on a conversation other than the casual hello's, thank you's and goodbye's with him to find this out. He does not always act in a professional manner. He will blame patients for HIS mistakes or things not going as he planned and talks down to the patients, showing his lack of professionalism. He needs to learn to be more tactful and less condescending. Many people do business with him, have no issues and do not share my viewpoint, while other DO agree with me and have experienced the same issues first hand. I am not prone to exaggeration. Save yourself the stress. You would be wise to choose a different Orthodontist who will behave in a more caring, compassionate and professional manner.
