I have been going to the Eye Center for around 6 years. I think the staff is really helpful and Dr. Sayegh is so kind and patient with all of his clients. He has a lot of experience and can explain hard concepts to make sure you know what's going on with your eyes.
When I was ordering contacts, the assistant let me try a couple of samples to see which one I liked most. After a couple of days, I went ahead and ordered which pair that was most comfortable.
To address the waiting concern: If you are in a hurry, I would suggest making an appointment at the end of the day or very early in the morning. Usually Dr. Sayegh isn't too far behind then.
