Dr. Cao was recommended to me by a friend. I had an excellent experience with her. She was very detailed with her exam and she definitely made me feel comfortable having my eye exam during this time of COVID. I know everything was already sanitized before my visit because at the end of our visit she mentioned she was going to sanitize for next patient. But even so, during our visit she sanitized in front of me again to assure me that everything was extra clean between patient use. She was very patient in answering all my questions and explaining until I understood and I would highly recommend her if you are looking for an Optometrist.
