I had an issue and they got me in to see the doctor in a limited time. They were very understanding and I appreciate being able to see the doctor before the holiday.

It would have been nice since this was our first visit if he had introduced himself. After Moms eye drops for dilation we sat for 30 minutes, I felt that was a little long. She even dozed off in the chair. Hoping the cataract surgery goes well and the after appts go well.
