Dr. Dao is very patient and professional. My daughter and i have been seeing him for more than 6 year and have neen very happy with him. He always give us good suggestions and advises on various situations. His office locations in Costco is also very convenient for us. When we visit him, we can also do our shopping at the same time.

Similar to other low cost prescription eye-care practitioners, generally a hurried in-out with little "personal touch" or customer engagement. Advice: go to this SFO Costco for your frames, but to a stand-alone Optometrist where you receive a degree of unhurried interest from the professional.
