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.

Professional service. Exceptional care.

Best in the Midwest
Had my fourth procedure with Dr. Riegel and his team last week. He and his nursing team are extremely professional and efficient. We have relocated, so this facility is not near our home. But the trip is always well worth it.

Dr. Riegel and the staff at Gateway Gastroenterology were excellent. Dr. Riegel made sure he visited with me and my wife after my procedure to give us the results and to make sure all our questions were answered.

Dr. Riegel is an excellent gastroenterologist.
I am very pleased with Dr. Riegel. He doesn't rush you through an appointment. He asks good questions on your gastroenterology issues. He is so very pleasant and listens to us patients if we have questions and very nicely makes recommendations if a different physician is needed for the issue. Highly recommend Dr. Riegel. Good doctor for colonoscopies too. The staff is very friendly and efficient. Excellent office.

Very disappointing. Can't get into to see him. Was told to go to the ER or urgent care and they would call me to let me know when they had an opening(at least two weeks). I starting calling him two weeks prior and could not get them to call back.

Dr Riegel has been my dr. for several years. The office is professional, conscientious, and follows up. Dr. Riegel has great bedside manner—knows his stuff and is kind. GI issues aren’t the easiest and he makes it better!

Best referral ever. Wish I had met him years ago.
Dr. Riegel is an instantly likeable person. One of my all-time favorite medical professionals. He's very prompt and respectful of my time. His front office staff is courteous and efficient as well. Many thanks to my Family Physician for referring me to Dr. Riegel.

I went to see Dr Riegel in November 2020 for my normal regular colonoscopy. He could not finish the procedure due to a blockage. He sent me to a wonderful skilled surgeon who preformed a colon resection. Dr. Riegel assured me it would be ok and the problem would be fixed and I would be good as new. I went back in June 2021 for another colonoscopy with Dr. Riegel and everything was great. I love the staff and he is a very caring doctor and explains everything to you. I have gone to other doctors and he is well above all the others. I would recommend him to family and friends in a heartbeat.

I had my first colonoscopy with Dr. Riegel today. I cannot not say enough about his kindness and concerns. I have RA and he took time to make sure I felt comfortable before the procedure. Hard to find a Dr. That has his experience and bed size manner. Wonderful Dr.

Virginia Miller – Nov 22, 2019

Was told I had IBS by Dr Riegel after several years being treated by Dr. Riegel with no results, I went for a second opinion. This doctor told me, no one my age is likely to have IBS. I was 80 at the time so I asked about Cologard as an option instead of a final colonoscopy, the scheduler said that medicare would not pay for Cologard, that I'd be better off with a colonoscopy. I appears that they do pay for Cologard, so either it was beneficial to the doctor to do the procedure or they were misinformed. I do not plan to go back.

I have never taken the time to write a physician review in the past, but I have to say I am extremely impressed with the outstanding care I received from Dr. Riegel. He took the time to listen to my concerns. He is incredibly intelligent, but more important he took the time to explain what was going on with me and options to improve my health. Working together, I feel better than I have in years. I would highly recommend Dr. Riegel as the best physician I have ever seen.

Dr. Riegel is arrogant and condescending. His colonoscopy prep is terrible and patients with slow digestive systems won’t be cleaned out. He diagnosed me with something another much more experienced GI doctor said I don’t have. All he cares about is staying on schedule.

Most doctors I run perpetually behind schedule. Dr. Riegel runs ahead of schedule. He spent an appropriate length of time with me and ensured that I had no remaining questions before ending the appt. I later called the office with a question. He called back - instead of a nurse or aide. Most unusual these days.
