Colorado Gastroenterology Reviews ( 143 )

  1. Horrible experience. I just want to change medication prescription due to insurance won’t cover. Its day 5, still not done and my wife still suffering pain.

  2. It’s been about 2 months and I still haven’t received a call or an email about my test results. This place is very unprofessional and every time I try to call no one picks up the phone. Consider going somewhere else if you have a choice.

  3. HORRIBLE EXPERIENCE. RUDEST STAFF DO NOT GO HERE. I was out of the country for 2 weeks and found out my work schedule changed, and they want to charge $50 cancellation fee when it is 24 hours in advance. Staff member was extremely …

  4. Dr Sieja is caring, thorough, and professional. He listened carefully, asked questions, and clarified expectations about my care.

  5. I like her writing down directions because I usually can’t write fast enough to get them down myself.
    She quickly gets to the point, and we are done with a hopeful direction to go next.

  6. If I’d seen a doctor more than once I’d have an opinion about the care. As it is I’ve had so much difficulty getting appointments that I don’t have an opinion about the care.

  7. The staff is friendly and prompt. I like working with Dr. Seija. He listens, encourages me to ask questions, empathizes and explains my health needs in a very understandable way. I’m grateful to have found him.

  8. This place is so trash! I have yet to even have a pleasant experience here. I had bloodwork done 9 days ago and still havent received a call back with the results.. Lab corp told me they sent the results back to the doc the NEXT DAY! Ive …

  9. Amazing! They actually answer their phone. They actually make an appointment when they answer the phone. How is it they can do that? No one else in gastro does that. “Sarcasm.” They took very good care of us totally worth the drive from …

  10. (this is Torie Vandeven, not angie rovetta.. she is my partner and emergency contact, fyi.)
    Dr. Brenner is an excellent listener and is focused on my particular health …

  11. Dr. Sieja listed to what I had to say. Scheduled appointments for
    me the very next day, in order to get to the root of my problem. I am thankful for having him as my doctor.

  12. Dr. Rufner was very knowledgeable and answered all my questions I had before I could even ask them. The prompt response and fast scheduling from them made my experience here way better than the last Gastroenterologist I was at.

  13. Dr. Sieja was very detailed and thorough in discussing the issues that I had recently experienced. He was able to clearly articulate certain things that I needed to change that included both lifestyle and dietary changes. I would strongly recommend Dr. Sieja for anyone that needs to consult with a Gastroenterologist.

  14. Dr Brenner was very helpful with my stomach and throat. She explained the 3 items that I may be having. She decided to start with a “Flip”. Scheduled this for Dec 26. After results, she will go to the next step.

  15. Had a job interview with this place. Scott Wingo promised me stuff that he did not deliver. Emailed and called him and no answer. Poor communication. So glad I won’t be working for this office.

  16. Dr. Rufner always takes the time to deeply listen to the GI issues I have faced, and then puts together comprehensive plans of how to move forward with treatment.

  17. If I could give 1/2 a star I would. Avoid this place at all costs. They took 6 vials of blood for my daughter. We called numerous times for results and finally after 2 weeks they said they had only received one back and that LabCorp had …

  18. Dr. Rufner really listens to what I have to say and can always make me understand what’s going on and make suggestions to help me. I would highly recommend him. He is a great doctor!

  19. If it matters, I had a good experience. My procedure was painless, I feel good the next day without any adverse effects. They even called the next day to make sure I still have a pulse. Never hard to get them on the phone and everything was spelled out nicely. I recommend.

  20. Dr. Brenner is a beautiful person,understanding and compassion she will take care of you and she always be concerned if you are following you treatments and helping you to get better and healthy to have a better life..she will listen to …

  21. I have spent plenty of time in doctor’s offices and hospitals and unfortunately am only 30. I have genetics that make me very prone to colon cancer, so I met with Dr. Frank and had a colonoscopy done as a result. They found a polyp, removed …

  22. They are the worst! I wish I could give zero stars and I’m really not one to typically leave a bad review! After calling multiple times and almost 2 months later the DR finally reads my results. The lab got them back to them pretty quickly …

  23. Make sure you bring a mask (unless you’re reading this from a post-pandemic world in which case, don’t rub it in), I forgot mine and almost had to miss my appointment because of it. Luckily there are nice dentists next door with masks to spare.

  24. I recently moved to Denver and I needed to get started on my Remicade infusion here. I was referred to Colorado GI and I will NEVER come back here. It’s been over 4 weeks since I was seen in the office and I still have not received my …

  25. My visit with Dr. Rufner was good but trying to communicate with the doctor and office is impossible. Six calls last week and no response. Makes me concerned about a response from him should there be difficulties after a procedure.

  26. Trying to speak to a person on the telephone is really really difficult. This is not a one time thing either. I waited on hold for 25 minutes today. Avoid this place if you want to be treated respectfully.

  27. Terrible, I have been going there for a few years. Recently, I try and make an appointment and all the calls go to a voicemail box that is full. So after much digging I find a number where I can actually reach someone. I make my …

  28. Dr Seija and everyone at the office are so lovely and professional. Sometimes there is a bit of a wait for an appointment because they are so popular, but it’s worth it. It’s always an informative visit and I come away feeling reassured with ways to manage different conditions.

  29. In August I had a colonoscopy with Dr. Rufner at the Golden location, and a few weeks later, my husband had his done in Denver. Dr. Rufner is the best in every way you want a doctor to be. He explains EVERYTHING and spends as much time as …

  30. Dr. Ruffner is the very best! He has His patients best interest at heart and is very much in tune with the needs of those that are lucky enough to have found their way to be in His s care!

  31. My experience with Dr. Rufner was incredible. He listened to my concerns and was very informative and polite. Will definitely be back here if I have any additional gastro issues!

  32. I had to wait for a while due to Covid and also a downed room computer, but I was kept informed and even Dr. Brenner came to the waiting room to let me know. I appreciated this. Another enjoyable follow up visit with Dr. Brenner and I left with the feeling that I was cared for and my concerns were addressed. Thank you.

  33. The staff were all very personable. All current safety guidelines were in place. Dr. Rufner listens, and discusses in detail your situation. He wants to be sure you understand, and does not rush the appointment.

  34. I have been working with Dr. T for over a decade. However…his staff is absolutely horrible. I should have been on a “maintenance plan” yet there was never any follow-up at all over the years… no return phone calls… in fact most calls …

  35. Excellent and informative tele-health appointment on July 15 with Dr. Rufner, who is always personable and who gets to the nub of the matter and explains clearly whatever action is next required. Inspires confidence. A+

  36. I have been to other Gastro office and this one by far has been 100 better than I could have ever expected! Dr. Brenner is amazing and seems to truly care about her patients! I would whole heartily recommend this practice!

  37. This is under Susie Arnold.
    Dr. Rufner is Amazing. He never makes you feel rushed. he explains everything, answers all your questions, draws pictures and always remembers who i am even …

  38. I saw Dr Brenner years ago and decided to do a follow up. She was as wonderful as I remember 9 years ago. Getting an appointment scheduled was not an issue, and I was happy to do a an appointment over the phone as well. Great experience.

  39. The front office was so kind and very helpful. I wanted to include this because the only issue I had was with the doctor himself. Thomas Trouillot was by far one of the most uneducated doctors in regards to celiac disease. I was diagnosed …

  40. All these bad reviews are true! Do not go to this place ever! I went one day as a walk-in, the staff said to come in. Then when I showed up, waited 2.5 hours, the doctor could not see me. So they rescheduled. I couldn’t make their …

  41. Both Dr. Rufner and Scott, the Front Office Manager, are best-in-class. Dr. Rufner has excellent bedside energy, and he is a very intelligent and thoughtful professional. Scott is perhaps the most proactive office employee I have ever encountered — refreshing! I highly recommend this office!

  42. I loved Dr. Brenner! She’s knowledgeable, focused, willing to listen, very straight forward (I like that) and caring. She’s down to earth, no beating around the bush, explains everything till you’re confident you understand. The office was …

  43. My partner Mark says Rufner is great, willing to spend time with patients. His office staff is personable, efficient, professional. Top notch service. Worked with my insurance. No problems.

  44. The office scheduled the checkin for the appointment during their lunch time. I’m not certain if this was due to new offices hours or not but the staff was very accommodating and apologetic. The appt was at 1pm but then the doctor was late. Hope we have a better experience next time.

  45. If I could give this place a 0 star rating, that’s what I would give! Got an appointment, requested all medical info to be transferred to them, including test results. The person, Julia, who scheduled the appointment guaranteed me that …

  46. The doctor is only as good as the office staff that is hired. I love Dr Rufner but he is not who you deal with on any everyday basis. The office staff is terrible. My experience has been lets say less than stellar. Wrong prescriptions …

  47. I’ve seen my fare share of gastro’s and Dr. Brenner had the worst bedside manner out of all of them. To a point where it could be seen as negligent. She brushed off my concerns and was very condescending. …

  48. Dr. Rufner thoroughly explained what he performed in a very understandable way. All the results were, also, communicated very well. He provided some suggestions on how to supplement my diet going forward. I would highly recommend Dr. Rufner

  49. My visit with Dr. Rufner was a great first meeting. He took all the time I needed to answer my many questions and make me feel very comfortable going forward with my procedure, especially in this time of Covid-19! …

  50. I had a colonoscopy with Dr Brenner she was so pleasant and made me feel comfortable. The staff and nurses that worked with her were absolutely amazing. So kind and caring. I would recommend them to anyone and I would definitely feel completely comfortable with Dr. Brenner handling any Gastrointestinal problems I had.

  51. I really felt heard. Dr Rufner was truly interested in my situation. I felt like I could trust him. I’ve not had great experiences with gastroenterologists and my expectations were low, dr Rufner completely blew my expectations through the …

  52. I can’t believe this place has as high a rating as it does. My experience with them has been beyond terrible. Virtual appointments that no one sends a link for. Appointments that the doctor doesn’t show up for. A prescription that still …

  53. Dr. Brenner was professional and kind. She took plenty of time to talk through my symptoms and took the situation very seriously. I really appreciate her ability to think beyond just GI possibilities, and her commitment to figuring out what’s wrong with me. I am so appreciative!

  54. Dr Brenner has always been very responsive to my illness and needs. I do have some questions about the side effects of the biologic she’s proposing but I am confident the she will explain completely!
    Thank you, Dr. Brenner!

  55. I went to see Dr. Rufner today, and the overall experience was fantastic. The receptionist was very courteous and friendly. I only waited a few minutes, and then was called into the medical exam room. When Dr. Rufner arrived, he took the …

  56. Dr. Rufner is a fantastic doctor—I can’t emphasize that enough. Probably one of the best doctors I’ve ever had. The problem is the wait time once you arrive for your appointment. Typically it’s 40-50 minutes after the scheduled appointment, …

  57. Dr. Rufner is awesome. In less than 30 minutes he explained to me about my multiple health problems and what could be causing them. Been waiting 20 years for some of the news i got today. …

  58. I’ve been seeing gastroenterologists in various cities for the past 20 years. Dr Kevin Rufner is BY FAR the most informative, patient, kind, and knowledgable doctor I have worked with. He is a member of various advisory boards and study …

  59. This is the best doctor experience I have ever had. Dr. Rufner is so kind and takes the time to explain everything so well. The office staff were incredible- kind and helpful!

  60. Dr Rufner listened carefully to my medical issue, asked me relevant questions and provided me clear explanations of my likely condition. Dr Rufner provided his plan to help me. I left his office with confidence that I am in very good hands with a knowledgeable and caring doctor.

  61. Dr Ruffner is a very informed and progressive physician who relies on his education, experience and collaboration with others to be effective for his patients. He has been the only physician who didn’t quickly dismiss my digestive issues as …

  62. Dr. Rufner is amazing! When I leave the office I feel like he listened to me and came up with a solution. He also explained in detail exactly why he was choosing a certain medication for me. After years of no explanation for my stomach pain, he found an answers for me. I highly recommend him.

  63. I felt that Dr. Rufner was very engaged and interested in helping me get closer to resolving my gastro issues. The initial consultation went well and I think that Dr. Rufner and his team will provide me the best possible care with any future issues I may encounter.

He was very professional and personable and I greatly appreciate him researching out my file prior to my office visit. He attention to detail and professionalism is greatly appreciated.

  65. I almost never do these reviews however, the office staff at this practice is sub-par…. while you listen to “on hold” messages about them caring for you as a whole person, some staff member sent my call to…. the abyss..and I literally …

  66. I am so saddened to write this review, but I am at a loss with this Doctor’s office. I saw Dr. Ruffner on October 28th and absolutely LOVED the care he provided. He listened thoroughly, was deeply knowledgeable, provided care complimentary …

  67. The nurse was SO funny and friendly, all of the people working in the office were sweet and helpful, and the doctor was so informative. I felt listened to and felt like I really understood the full extent of the processes I was going to go through.

  68. Dr. Rufner surprised me with his attentiveness and listening skills. He took his time making me feel extremely comfortable and confident in my care plan. He told me his goal is to make me feel empowered.

  69. I’ve seen Dr. Kevin Rufner for a few visits over the last year while we get my treatment plan changed up, and I’m extremely satisfied with his care. I’ve had IBD for 40 years, and lived in different places, so I’ve seen many GI Docs over that time. You won’t go wrong with him as your GI Doc.

  70. Dr. Rufner is excellent. This was only my first appt. so I will come back and update this review after my second. I was able to really talk to him and tell him everything and he listened really well and explained in detail what I needed …

  71. Dr Rufner was fine (first Gastro experience so…) but I find it hard to trust any medical provider that doesn’t have an option to pay the bill online. Do you really want me to put my CC info on paper and send it via USPS in this day and …

  72. I saw Dr. Rufner on the 1st of November for an ongoing, intense internal infection. While he did seem very knowledgeable about how to proceed, he never completed the order for the medications we had discussed. I reached out to his medical …

  73. I have been a patient of Dr. Kevin Rufner with Colorado Gastroenterology for many years, and it has always been a positive experience. Dr. Rufner is a kind and caring human being who really listens to his patients. He never makes me feel …

  74. Dr Rufner does his best to understand his clients needs and make a plan with their goals in mind. He looks to help to recommend for wellness considerations, not just diagnose the IBD and check in once a year. I have been very satisfied with …

  75. Dr. Rufner is very friendly, easy to talk to and was spot on during our initial consult however, I have been trying for 2+ weeks to call the office back from my results to no avail. Tried many times at different times of the day for 15 min …

  76. Dr Rufner was extremely friendly, but communication and follow up from the office is poor. I called multiple times and still haven’t received bloodwork results. Today I found out they put my insurance in wrong so I have now been on the …

  77. Do not go here. My husband saw a doctor here for a heartburn issue. The doctor recommended a throat scope and a colonoscopy. Fast forward to three days before the procedure. They sent an email that a new medication was needed for the …

  78. I have never been discriminated against for having a mental health diagnosis until I went to Colorado Gastroenterology. My experience at Colorado Gastroenterology left me crying outside of their offices. Dr. Brenner completely ignored all …

  79. I have been a patient of Dr Trouillot for many years. He has always been attentive and open to answering all my questions and concerns. His care has resulted in total remission of my UC. I could not be more satisfied with his his care and the service provided by his staff.

  80. I have been going to Dr Rufner since 2014 when my pancreas blew up. Dr Rufner has been my rock ever since and helped me walk through a very rough road of multiple ERCPs (over 12), stones and major surgery. I feel like I owe my health and life to him. He is extremely knowledgeable, kind, calming and you cannot do better than Dr Rufner!

  81. I will change my review if I get a positive response from the doctor. I switched over to this practice and was happy until they didn’t want to refill my prescription I’ve been on since 2011. The part of my intestines that distributes b12 …

  82. The doctor I saw shamed me for being anxious. She completely dismissed my symptoms and wouldn’t listen to me when I tried to explain how my stomach problems weren’t merely from hunger. I’ve never felt so disrespected or dismissed by a …

  83. If I could give no stars I would. I went to this office personally to help my mom get information about a procedure she needed and the receptionist had the rudest face and tone while talking to us. She was incredibly dismissive as was Linda …
