Even though I missed the appointment time they had me scheduled for, they said” No problem. We will work you in. Thank goodness!

I had very good experience with Dr. Riegel and team when I had a colonoscopy on 12/10/25. They sent me information way in advance so I was ready for the prep and the procedure. On the day of the procedure they actually got me in early. Nurse Sarah and nurse anesthetist Erika were both professional and very pleasant. Dr. Riegel checked in with me beforehand to make sure I was good and to answer any questions. It was over before I knew it, it couldn’t have gone better. I would highly recommend Dr. Riegel and the team at Gateway Gastroenterology,

I appreciate the time Mrs. Carmody took to review and explain the issues I have been having.

Dr Matthews is very professional kind

As usual an appointment with Dr Haas is informative and enlightening. I do really like him.

Cheri was wonderful! Highly recommend her. Very professional, knowledgeable and sweet. This is why I prefer NP's over an MD every-single-time, that I visit a "Dr's office.

This is my fourth colonoscopy with Gateway. Like before, everyone is friendly, knowledgeable, and professional. They patiently explain every step of the procedure and continually check for understanding, ready to field all questions. Dr. Ramgopal made me feel comfortable and confident regarding the procedure, and afterward he took his time in reviewing his findings. Getting a colonoscopy is not something I look forward to, much less four times, but Gateway has made it as pleasant an experience as humanly possible.

Every thing went well and the nurses were very good and I thank Dr MCMORROW for everything he did and was a very nice person

Great Dr. and staff. Very friendly and explained everything very well.

Communication with your staff was very good. Getting the prep was easy, mailed instructions arrived in plenty of time, pre-proceedure phone call was helpful, nursing staff was very nice, I really liked the CRNA, follow-up call to check on my recovery was appreciated. I did call to get more detail on what I needed to stop eating five days in advance. I'm sorry, it didn't occur to me that my daily vitamin has iron in it which may have affected my prep. I'm a little sketchy about how to set-up a portal, but I'm sure we can figure it out. Thank you.

Dr. McMorrow is one of the few doctors I have visited recently that is will to spend time with you and answer all of you questions. He performed more of a physical on me than I got from my GP recently. When I asked him about any liver issues he said stay put and I will go look at your recent blood work. When he cam back he said all looked good, which make me very comfortable. When I told him I was concerned on weight gain he has recommend a dietitian to work with me.

From the humorous side, Thanks to Dr. Morrow for a great time. The experience was with staff and Dr. Morrow was great.

Dr. Keim was well prepared for my visit. She was exceptional in her knowledge of what was going on with my health and concerned with covering my needs and any concerns. She explained her thoughts about possible issues that I could have. If I have any questions I wouldn't hesitate to contact her.

Dr. McMorrow listened to my concerns ,explained in detail the possible causes of my Current condition and ordered the appropriate tests so that he can prescribe the correct treatment .

Dr. Ramgopal is wonderful, He is so kind and attentive. He took time with me and listened to me and gave me ways to help me with my situation. I highly recommend Dr. Ramgopal.

Dr Romgopal always takes the time to connect and ask questions about your overall health. He remembers me from visit to visit (just over once a year), very comforting and knowledgeable. I am thankful I found him and he helped educate me on how to handle my health situation the best way possible. Highly recommend him!

Ms, Schild was thorough, helpful and knowledgeable.

Great staff.Great communication from entire staff. Procedure done without a hitch

Unlike all of my previous colonoscopies After I arrived home I had terrible discomfort around my rectum. 2 ibuprofen helped quite a bit but the pain was so bad I was unable to sit. I used prep h to help as well. After a nights sleep I feel much better today.

Felt at ease no concerns at all

My experience with Mrs Carmody has been outstanding! She is thorough, kind, and knowledgeable. She asks pertinent questions, as well as really listens to your responses and concerns. I highly recommend her as a caregiver!

Attentive and qualified staff supporting a well trained physician

I was treated with dignity and respect by the staff and doctor. Which made an unpleasant procedure tolerable and painless. Thanks to the entire staff!

I always get great care here.

I had a great experience with the staff and the doctor.

Very good very thorough and my nurses and doctor haas were very nice so thank you for taking care of me.

Thorough, friendly and helpful!

Always listens and very good at communication.

Dr. McMorrow is the ONLY Dr I have ever seen who walks in having already read your chart, remembers your history and knows what is bringing you in so he can immediately start addressing your concerns. I hadn’t been in in almost two years and he was still up to date with what we went over on my last visit and asked great follow up questions. And ON TIME! I did not feel like a number to him. Also, this may just be me, but I appreciate the old school use of pen and paper to take notes while making eye contact. He wasn’t sitting there staring at the screen and typing away. I’m sure he used a laptop after he walked out, but was sure nice to be looked and spoken to while questions being asked.

Very caring and very good listener.Nice knowledgeable visit

From the appointment setting through the entire colonoscopy procedure, Dr Ramgopal and his wonderful nursing staff were excellent communicators and caregivers. I am very grateful for their kindness.

Dr Haas was very pleasant to talk to. He was very informative about my procedure, before and after. If I need similar procedures in the future, I would definitely try to come back to Dr Haas. He was great.

I am very pleased with my experience with Gateway Gastroenterology and highly recommend Dr. Mathews, who is excellent and worthy of a 5 star+ rating in all points. Prior to this appointment, due to fear of having a colonoscopy, I had waited 15 years past the recommended time. Due to health issues, it was also fear that caused me to pray, seek a highly recommended Gastroenterologist, then schedule an appointment. I am thankful to God and to Dr. Mathews and his team for taking good care of me.

So comfortable and relaxed…informative and bedside manner was outstanding. Her questions, suggestions and examination were great. She was a breath of fresh air in what can be a complicated medical environment. Thank you from my heart.

Dr. Carmody was very helpful in diagnosing my situation. After meeting with her, she passed me on to her medical secretary, Cindy Schulte. Cindy was the most personable, patient, and professional medical secretary I have ever worked with. What a special young lady.

I had an appointment at Gateway Endocrinology a couple of days ago. The medical secretary (Cindy Schulte) that helped me with scheduling some images was amazing. She was very personable, very professional, and was on the phone for 20 minutes coordinating an appointment for me.

Dr Hass is excellent. Explained everything well. Took the time to answer all my questions. Very caring and compassionate and easy to talk to. Helped me make some difficult decisions. I would highly recommend him to anyone with any GI concerns.

Dr Williams really listened to me. I didn’t feel rushed.

Excellent professional, you can expect a clear explanation of procedure with an excellent treatment from all staff members.

Dr Matthews has it all....great fund of knowledge, ability to answer questions in an understanding manner and makes you feel he has all the time in the world though it's clearly a very very busy practice....funny how that happens to the good docs :).

The doctor and the nursing staff were very friendly, caring and informative. In fact I was given two warm blankets prior to my procedure. It seemed that everyone enjoyed their job and it came through in the way I was treated. The facility was clean and up to date.

Dr Ramgopal & the entire staff were smart, efficient, kind & caring.

He was super helpful!

Thank you for taking the time to answer my questions & make me feel comfortable. I felt like you cared & you took the time to just talk to me. Thank you again

Everyone from the receptionist to Doctor Ramgopal were top notch

Always professional, efficient and respectful

Cheri was well prepared to discuss my situation with gastrointestinal issues over the years. I have been the doctors in that office and Cheri for well over 20 years, which included 5 colonoscopies/5 endoscopies during that period. Cheri gives excellent advice on what medicines to use to relieve the discomfort associated with my discomfort through the years. I applaud her efforts and the entire staff.

I was exceptionally pleased with the care and the professionalism that I experienced. Dr. McMorrow and the staff were expedient, kind and caring.

Dr. Haas was very good at explaining the situation and the importance of diet. He helped me by setting realistic goals I feel I can accomplish.

Staff was very helpful and Dr.McMorrow took his time to explain what needed to be done.

Dr. McMorrow is a knowledgeable, efficient, kind and compassionate provider and I highly recommend him.

Anyone needing to lose weight but putting it off should listen to Cheri Carmody! She’s knowledgeable, persuasive and kind.

Very nice, great bed side manner.

Dr. Ramgopal was very personable and took time to listen to my concerns and address each one. I feel very at ease with him and am confident that he can resolve my problems.

Very polite and made me feel comfortable from the moment I walked in.

Personnel were friendly. Admission process involved some duplication of information which could have been more streamlined. Setting up the IV was difficult due to dehydration but staff were caring and gentle in their efforts. Dr. Ramgopal and Jill, the nurse anesthetist, did a great job. The doctor took an appropriate amount of time to explain the results.

First time meeting Mrs. Carmody. Very professional yet friendly. Asked pertinent questions and had positive comments regarding future episodes.

It is always a pleasure to visit Dr Williams. He listens, explains everything thoroughly and asks about your concerns. The office staff is very friendly and waiting time before seeing the doctor is short

I had not met Dr Haas prior to my procedure. He was filling in for a doctor who had an early delivery. He was very communicative, great bedside manner, answered all my questions before and after. I did not feel rushed to “get it done”. I miss Dr. Williams (all the best in retirement), but Dr. Haas was great and I’ll see him in 5 years! Thank you

Great communication, efficient and everything running on time! Staff very friendly and professional. My nurse, Nikki, was excellent! Give that girl a raise!!

Everyone and everything was wonderful!

Dr Riegel is not only a great doctor but a kind, caring wonderful man. I always look forward to my visits with him. His office staff mirrors his personality and makes the overall experience delightful.

Dr. Ramgopol is friendly, thorough and listens to his patient. He involved himself in other aspects of my health which was appreciated. I highly recommend him as a gastroenterologist!

Dr. Haas was comforting. Although I just met him a few minutes before and after waking from the procedure, he spoke with me and my husband like he’d known and cared about my health for a long time.

Dr. Ramgopal is very good and talks you through the procedure to be done. After the colonoscopy he explained everything very thoroughly. I recommend him for everyone.

I was able to watch the entire procedure and he was extremely careful and gentle with me since I did not use any anesthetic. I highly recommend him and his entire team.

This was my first visit with Dr. Williams. He has a caring attitude about him. He listened attentively to my list of physical problems, dealt carefully and thoroughly with each, outlined a course of action for each, answered my questions until I understood and agreed with his plan.

Absolutely outstanding in every way. Knowledgeable, thorough, a very nice person, caring and more. He shows a genuine interest in the welfare of his patients. In my case, he was able to diagnose a serious problem that other specialists didn’t, and put me on a path to health. He has my highest possible recommendation.

This was my first contact with Dr Riegel and it was a wonderful experience. He listened to me, took the time to explain my conditions, and discussed future treatment options in a friendly and comfortable manner.

I was very pleased with our discussion and have scheduled a colonoscopy with him.

Dr. Riegel and his staff are wonderful!

Dr. Jeffrey Mathews and all the staff made me feel real comfortable and relaxed. I had a great experience before, during & after my colonoscopy

I saw Dr. Kreikemeier for many years until he left and then I saw Dr. Seccombe and he left. I finally feel better being established with Dr. Riegel and I am so grateful I received a "better" diagnosis re: my IBS.
