Don't waste your time..
No need for an appointment because I waited over an hour WITH an appointment! Not only that the frames are overly priced. However the front desk ladies were great and that was the only reason why I waited. I highly do not recommend going here.
Dr. Dang is so nice! She makes you feel very comfortable and she does a great job at explaining any questions you may have. She has two offices, one in Garden Grove and one in Westminster. Both offices have a good selection of frames to choose from and helpful staff. I've also had exams with the associate optometrists as well. If you have some time on your hands and want an extremely thorough exam, go with Dr. Pham. If you're on a time crunch, schedule an appointment with Dr. Sea. All the doctors are great!
