Frankfort, IL

Dr Kosek and his staff were amazing. Sue and Pam were always extremely helpful with frame selection and keeping us up to date with insurance and coverage. This new staff and Dr do not even come close. After being there for 2 hrs, I walked out with nothing but aggravation. No new glasses or even a prescription to get some at another place. Dr Kosek and his staff will be greatly missed.

We have been going to Dr. Kosek's practice for at least 10 years and have always been 110% satisfied. Everyone in the office is friendly, helpful, and very knowledgeable. Dr. Walsh is wonderful with our kids and we love her too. Highly recommend!

I went there for the first time, recently for an eye exam. (They are on my insurance plan) The staff was extremely friendly. Dr. Kosek was wonderful. I was very happy with my first time visit. I went for glasses, although I didn't find a frame that I liked this time, they said they always get new ones in. I also scheduled a contact lens appointment as well. I will be coming back here for my exam next year as well.
