The last time I was here was 2012. I rolled up with no appointment today around 11:00am for an eye exam but the earliest opening was 12:20pm and another at 1:40pm. I opted for 1:40pm and went on my way... 5-10 minutes later I get a call saying there's a spot opening up and if I was near.
Turned right back around, got in, filled out short paperwork, waited 5-10 minutes and did the prelim stuff, waited another 5 minutes or so and did the actual exam with Dr. Roter.
Very professional and efficient. Was in and out in no time.
Definitely recommend an appointment though if you don't have the entire day open.
Will see again in 5 years?
