    verry good team work

  • Jan 31, 2019

    My experience with Dr. John Clements is just fine. He's always very friendly, very informative. He really treats me better than I deserve. No, he's just fine and that's roughly about it. I'm very happy with Casey Eye, and that's about it, I guess. Okay, how do I in this? I wonder that's it. Do I hang up now? I don't know what to do.

  • Jan 30, 2019

    very thourough, very courteous, very professional

  • Jan 30, 2019

    Very positive

  • Jan 30, 2019

    Yes, he's a very good doctor although it's kind of hard getting denied for the work on my eye again.

  • Jan 15, 2019

    I was extremely sad to hear he is leaving Casey Eye Institute. I thoroughly trusted Dr. Clements. He has been crucial to my on-going eye care.

  • Jan 10, 2019

    Dr. Clements is a very caring and knowledgeable eye doctor. I would highly recommend him I've been see my son has been seeing him for over a year and... he's he's amazing. He's wonderful.

    John Clements has been my corneal ophthalmologist for almost 5 years and he is taking me through enormous challenges. He has always always been willing to share information with me. Listen to the information that I brought to him and he has done a spectacular job. It is a polling to me that you're losing him. I will no longer be coming the Casey Eye Institute because he will no longer be available to me as my corneal specialist. So there you have it.

  • Jan 02, 2019

    The Doctor explained things in a simple easy to understand way so I would know what exactly was going on with my left eye.

  • Jan 01, 2019

    I will miss Dr. Clements and wish him all the best! He is a great doctor! Dr. Werner saw me for the most of this appointment. He is a very caring and thorough doctor who has helped me regain the health of my cornea!Thanks so both of them!!

    Dr. Clements is the best. He's patient. He's thorough and made me feel extremely comfortable with traumatic situations in my life. And I'm sorry that he's leaving. Can't you keep him? He's the best I give him a 10 off the chart.

    I think Dr. Clement's is one of the most professional people I have ever met. His knowledge is great. His friendship is fantastic. Everybody in the Casey Eye Institute really impressed me. I think it was fantastic. I cannot say enough good about them. So anyway, it's a plus. Did you get that?

  • Oct 31, 2018

    I had an appointment at 4 o'clock and was not seen until 5. Although he was very good about it and took care of me and explained things to me and referred me on and said that I needed further help. So, that has come through and I'll be doing that. So it was a good... it was a good experience. Thanks.

  • Oct 16, 2018

  • Oct 03, 2018

    Being barely on time for appointment, contributed to a longer wait possibly, but overall, 15mins is not bad! All went smoothly, and that's positive.
