"Dr. Kliewer is an excellent doctor who has performed a Colonoscopy on me twice to remove polyps and insure my health. The office staff is great to work with and everything is done efficiently and well. At the end of each procedure, Dr. Kliewer sat with me for a consultation to show me pictures and review his findings and prognosis. Having had colon cancer in my family history, I continue to know that I am healthy, and if something were to appear, it would be caught early. I feel confident I am in good hands."
"Dr. Kliewer has accomplished all four of the colonoscopy procedures I have had over the years and he still does an excellent job. He is extremely personable, and easy to converse with about the procedure. Great bedside manners and keeps the patient first and foremost in mind during the preop, actual operation, and post operation process. I highly recommend him and his staff."
