Have been a patient for several years with excellent service from staff and Doctor Dieck. Never feel rushed. His manner is highly professional and thorough. He has a great sense of humor (a rarity these days)/Always feel my eye health is in great hands. Highly recommend.

Worst doctor I have every seen. Just wants to move patients, lied about prescription dosage, says he will call, never does. Had zero bedside manner and could care less about his patients. Waited 45 min both visits, no apologies...tried to get your out in 2 min to keep the money churn going All he does is belittle questions as if he is the best doctor in town (Clearly is not). New doctor I went to said he has a bad reputation and many of their patients come from poor experiences with Dieck

I had an eye abrasion on a Saturday afternoon and he met me at his office an hour after I called. My original eye Dr. said he would see me the following Wednesday. Guess who is my primary eye Dr. Now
