I have been going to Dr. Dao for many, many years. She has always been professional and cares about each and every one of her patients. I have never had a problem with wrong prescription or having to wait too long for my glasses/ contacts. When I first started wearing contacts, Dr. Dao went out of her way to make sure i was comfortable putting them in and taking them out. I will be going to this doctor for a very long time. Dr. Dao is amazing and i will refer everyone i know to her.
