On his website he says that he's financially independent from the optical store next door, but I don't know if that's so true. I was on hold to ask a question about my prescription and got transferred to the store next door, without being informed that I was being transferred. I spoke to a rather brusque man who started discussing my prescription with me and seemed to have complete access to my file.
Pros: Fairly easy to get an appointment
Cons: Privacy issues, doesn't inform you of your options.
