Dr, Diegel is very friendly and helpful. He took a lot of time helping me pick out frames that I would not have considered on my own, but were great for my face and coloring. He is very exact in his exams. He managed to put me in trifocals that I tolerated very well. This was an accomplishment as others including Dr. Ossip and the Lenscrafters - Glendale optometrist failed in this. I reccomend him strongly and I am a very particular patient. Dr. Joan Farrell
