Your trust is our top concern.

We strive to keep reviews honest, trustworthy, and fair.

Doctors can not pay for good reviews, nor can they pay to have negative reviews removed.

We monitor all reviews to ensure they comply with our guidelines and don’t include personal information, profanity, libel, defamation, harassment, obscenity or fraud.

Any reviews that are deemed fraudulent or violate our guidelines will be removed immediately.

All reviews are confirmed and audited before publication, and community members have the ability to flag inappropriate content for further review by our team.

Definitely recommend to anyone
I had to do a visit prior to procedure due to having a stroke. Dr Kliewer was very informative and knowledgable about my medical issues and put my mind at ease. I still have to wait a few more months but I know that I will be in good hands. I would recommend to all and friends.

Would not recommend
If you are a patient at St. John’s or referred to him by a St. John provider you will be made to feel as an inconvenience. Mention was made several times as to how hard it is to acquire medical records and how their surgeons don’t take proper biopsies for his purposes so in order to offer any advice plan to wait and leave frustrated. Possibly even needing to have the same scopes done if he didn’t like their findings. Was advised to lose weight and use an app on paper but did not ask about my current weight loss journey even when told I’ve tracked every bite for months during appt. Lastly as a woman my heart rate was checked by him using a flat open palm on the entirety of my breast tissue. Never in my 42 years have I felt that uncomfortable after an appointment with a doctor. I did speak to the office manager and she apologized for the experience but when I was prompted to leave a review by text I thought I could spare another from a similar experience.

A Credit To The Industry!
I've definitely become 'disenchanted' with the medical industry but some digestive issues forced me to lay it on the line. Not only was his office incredibly kind, I was able to get in as a new patient insanely quick. He was really attentive to what I was saying, and even took the time to leave and review some previous tests I had done at another facility, then came back and spoke with me more. I would highly recommend!

The front staff was very polite, helpful and organized. The nursing staff went above and beyond what I was expecting. By the time it was my turn I was comfortable, not anxious. Dr. Kliewer was very informative, made sure I understood the procedure, took time not rushed. Recovery nurses were so sweet. I have recommended Dr. Kliewer to my family. Thank you.

This guy was unexpectedly awesome. Sometimes dealing with docs I remind myself to lower expectations but not so with Dr. Kliewer. He is quick and yet generous with information. He will be direct with you (which I appreciate) so be ready for that. Referrals have been fantastic and timely. His staff seem very organized, efficient and friendly.

Dr. Kliewer was very professional. I had never met him before my procedure as he is in Tulsa and only comes to Enid on certain days. The procedure was quick, painless and he went over results with my husband. I would use him again for a colonoscopy.
