I would readily recommend others to see Dr Sylvia Chang. Dr Chang is personable and caring; gives brief affirmative responses without needing to be asked first. We even talked about pickleball!

I would never recommend this dr, she was very rude with me and didn’t try to help me with my problems after a cataract surgery after 2 months I was really waiting for her to help me and now I have to wait another month to se a different doctor Not very happy because my eye is really bothering me very much
