Perfect! My husband and I were 2 hours late to my appointment. (We had a slightly wrong address!) We were both traumatized and exhausted by our 2 hour drive of getting lost. It was long past my appointment time and I am crazy to tShow morehink that I am going to have to repeat my prep again. To our most pleasant surprise, we were greeted by the staff and Dr. Riegel who was calm, cool and welcoming. They never mentioned our extreme tardiness. They simply brought us directly to the back and started prepping me for my colonoscopy, which proceded in a speedy, but not rushed manner. They couldn’t have treated us better if we had brought lunch for them all! Everything went smoothly, and after the colonoscopy they told us that they would never leave before a patient had been seen. They wouldn’t want them to have to go through the 2 day prep again! WOW! That is what I was afraid of the entire 2 hours we were driving around lost. My Colonoscopy went smoothly . The Dr. and his staff are top notch, both technically and personally. Wow, what a wonderful experience we had!! By the way, my previous gastroenterologist had recently retired and this was my first visit with Dr . Dr. Riegel and his staff! Wow, am I impressed! Thank you so very much!!!

Mary Q. • January 28, 2023

My experience was great, the front office prior to the actual event had a lot of issues. They sent me the initial paperwork with the date, time and doctor performing the procedure HIGHLIGHTED and it was all wrong - it said a dateShow more in 2014 and a doctor that has retired! I have to say that did not make me feel totally confident in the facility. Then they prescribed a $200 prep that the pharmacist was never able to see if my insurance would cover or not, after standing there for 15 minutes. I called and got a new prep for $0 and they said they would email instructions, to not follow the instructions on the box. That email never came so I called for a third time to get it. Everyone I saw on Thursday was awesome and I was totally at ease, but you need to take a look at your office people.

Check in was easy and I had a short wait. The nurses, anesthesiologist and doctor explained everything in detail. Before I knew it the procedure was finished. I especially loved the warmed blankets!

Shelley G. • January 17, 2024

Was unable to make my appointment in person due to an illness and when I called to reschedule they offered me a telemedicine visit which was great. Doctor was very nice and answered all my questions.

Christopher F. • January 17, 2024

Procedure was explained to me prior to testing. Staff was very friendly and addressed concerns that was on my mind.

Marlene L. • January 06, 2024

I was timely received by the doctor. My situation/issues were carefully analyzed and addressed. I was given a remedial plan to follow and instructed how I should report results to the doctor. As doctor's visits go, this one scores100%. I do not see how it could have gone any better! Robert S. Mullen 1/6/2024

Robert M. • January 06, 2024

Everyone is very nice and it’s a very efficient operation. Great place!

James M. • January 04, 2024

Everything went right as scheduled on time. The exam went fine no problems afterwards the doctor and his staff very professional

John C. • December 18, 2023

Everyone in the practice from staff to nurses to anesthesia to Dr. Riegel provided friendly, courteous, professional medical care. I have been seeing Dr. Riegel for 23 years and this level of patient treatment is difficult to beat.

William S. • December 17, 2023

Very professional before, during, and after the procedure. Highly recommend.

Matthew W. • December 16, 2023

This truly a professional group. From the personal phone contacts prior to the day of the procedure to the front desk administration and finally to the nurses and doctors, everyone treated with high respect. I could not ask for anything more. Everything went very well

David R. • December 15, 2023

The F.N.P. I met with was very attentive and easy to talk too. A negative of the practice is the doctor I was going to left the practice and his customers were not informed. When I tried to see another doctor I was told it would be a three month wait. I guess there is always the emergency room if needed. I was happy that I was able to talk to Mrs.Aubuchon that only took a month to see her. I have now reestablished myself with another doctor in the group.

Edward S. • December 14, 2023

Alwats such a pleasant experience at Gateway Gastroenterology. The dr and staff are amazing

Pamela R. • November 30, 2023

Friendly, easy in and easy out, compatent.

John R. • November 27, 2023

Very pleasant and efficient. Answered all my questions.

Jeffrey W. • November 23, 2023

Staff is friendly and efficient. Liked Dr. Rigel. My only suggestion pertains to the prep instructions. My colonoscopy was scheduled for 7:00 AM which meant I needed to be at the center at 6:00 AM. The prep instructions were to drink the solution at 2:00 PM the prior day followed by the second at 10:00 PM. As a result, I only got 2 hours of sleep that night. For the early morning appointment, I suggest starting the prep earlier, or at least moving the second round to 8:00 PM.

Patty T. • November 17, 2023

Very knowledgeable and helpful concerned with my wellbeing

David H. • November 17, 2023

My experience was great. The Dr. Riegel was attentive when describing my symptoms. He explained what the next steps would be for the exams, he also explained about the exams. The clinic staff are also great! They were very nice.
