Dr. Kleimeyer did a superb job of explaining a complex situation in language that was clear and easy to follow. It was obviously important to him that I had a good understanding of my problem and the possible solutions. I am very pleased with the care plan we worked out and with my care today.
He’s Fabulous… the Best he’s great
Well prepared, Explained things in a way I could understand, Calm and collected, Confident and reassuring Very nice bedside manor
He was very nice. He did not rush the conversation and he answered all my questions.
He always talks down to me. Lacks empathy. Minimizes my concerns.
I so appreciated how he listened to me, how he made me feel like every concern I had was valid. He genuinely cared and showed that in his responses, his active listening and suggestions on going forward. He made me feel like I mattered.
Very accessible, easy to talk to, listens well, answers the questions succinctly and accurately.
I trust and appreciate having John Kleimeyer as my doctor.
Seems professional and thorough in order to completely get to further ways to pinpoint a good diagnosis and plan for treatment.
John clearly has knowledge and experience with the spinal and related nerve condition, as well as sufficient and effective surgery solutions. He proposed a solution that is much less invasive than a local surgeon proposed, much to my relief. I feel more comfortable in that solution as being just as effective without unneeded and complicated hardware. I have a strong sense of confidence in John's recommendations. Should it become necessary to have surgery I will return for it.
Feel like he is very thorough and listens to us. Also explains things well
He is a very caring and smart Doctor and he wants to help you decrease your pain. He was willing to help me when other Doctors told me there was nothing they could do.
Excelent visit very informative and through!
I brag about Dr. Kleimeyer all the time. He is one if my all-time favorite doctors and I have and have had some great ones. He’s in the category of “great!â€
Dr. Kleimeyer was the first surgeon in over 15 years that actually pinpointed the problem in my lower spine. Now post surgery, I can only hope the surgery reduces the pain to a point where I will no longer require medication to sleep at night.
Dr. Kleimeyer has been a miracle worker and I can not than him enough for taking as good of care of me as Dr. Caragee used to. Being referred to Dr. Kleimeyer was the perfect replacement for me and I also want to thank his entire staff as they were all terrific!

What I appreciate it about John Kleimeyer was that he was prepared for my appointment. I had a previous MRI he had that with him and we did talk about it and how to move forward from the results of that. I only wish I would’ve asked him did he see a significant difference in the MRI from the year before. But we discussed a strategy moving forward and I was very happy with the direction Dr. Kleimeyer is going in & I understood him clearly. Thank you Dr. Kleimeyer!
