The staff is excellent. Kayla was super helpful. I needed assistance with the temple ends on a vintage pair of Rayban glasses. She replaced them perfectly. She also adjusted them to fit my face better than they were prior. I will return to Dietz-McLean for all of my optical requirements. Thanks Kayla for the top notch service.

I have been a client for many years and have always had great service. I just picked up 5 pair of eye glasses and they fit them well and got the prescription perfectly.
