First I must say that Dr Diep is good at what he does however the new doctor that he hired sucks.. THe last 2 years I have seen Dr Nikki and for the past 2 years she has not been able to get my contact prescription correct. It don't mind going back to get my contacts corrected, however, Dr NIkki has consistently blamed the "dry" weather or allergies for the contacts not fitting comfortably.. For the last 2 years she has given me eye drops to go home with in which I am to use for a week and than continue use of my contacts. I also got charged 80 dollars for a follow up for her to tell me that.. I thought when a doctor writes a prescription and it is not fitting correctly on a patient they are suppose to provide free follow ups until the contacts are right!! This year I am in phoenix and i have seen a new doctor, not only are the prices for glasses/contact lenses much cheaper, but the doctor doesn't blame their patients for what they initially couldn't get right. I"m paying 1/2 for contacts and glasses than what I paid at Dr Dieps and I get MUCH BETTER SERVICE!
