Dr. Wong is very nice, efficient and thorough. She explained everything to me as she was doing the exam. Went over findings. Made recommendations and a plan of action. It is great that there is free parking. Her office is very nice and spacious. For my first time ever visiting an ophthalmologist, this was a very good experience. I highly recommend her.
