I live overseas and had less than a week in Phoenix. Many offices told me that a consultation and creation of the glasses was impossible to do - especially given that it was over the Christmas holiday weekend.
The standard service at CPEC in itself is deserving of 4 stars, but what makes this practice truly stand out is their willingness to accommodate patients' needs. Dr. Kantor and his friendly, well organized staff went out of their way to schedule me for an early morning appointment and then asked the lab to rush the glasses.
