"Jun 2024 Dr. Rufner performed an endoscopy and colonoscopy on me this month. I greatly appreciate his diligence in determining the cause of my symptoms and offering expert health recommendations. In my opinion, he's an awesome doctor. I feel confident trusting his diagnosis and course of treatment. He's thorough and takes time to explain his diagnosis and treatment options. He never gives me the rush-act. He's caring and compassionate. I highly recommend Dr. Rufner for your gastroenterology needs. Oct 2023 Dr Rufner is excellent! I love how he drew a picture of what was going on. He knew what the problem without ever physically examining me. This doctor really knows his stuff! He spoke quite authoritatively regarding my diagnoses and offered valuable explanation regarding his determination of what was causing my symptoms. I felt I could place my confidence in this physician because he was transparent as he offered knowledge about what was causing my symptoms. I felt better emotionally, mentally, and I began tfelling better physically after following his prescription. I highly, highly recommend Dr Kevin Rufner and his medical office. The office staff were excellent. I will definitely recommend this gastroenterology practice to my friends and family."
"Dr. Brenner is kind, funny, knowledgeable, and approachable. I immediately felt at ease the first time I met her. This is a good trait to have when you are treating a patient. I would highly recommend her to my family, friends, and anyone else for that matter. Emily L."

"Colonoscopy: If you need to have one, Dr Rufner in Lowry is the GI doc to see. Dr Rufner teams with experienced anesthesiologist and nurses. He was one of Dr Mallory, retired GI who taught gastroenterology at UC medical school to this generation of doctors. Would recommend using zinc oxide/ diaper rash ointment BEFORE drinking bowel prep. Takes 72 hours to rebuild your microbiome."
"excellent competent and friendly staff. from front desk, to Scott, the doctor and finally young lady doing scheduling were great. very efficient and well informed. highly recommend"
"Prep routine was the worst part - surflava tasted terrible and had a slimy texture - gag index was high - left me feeling queasy. Procedure was easy, check-in was efficient, all my concerns were addressed, and everything was fully explained. Some of the staff didn't seem to have much of a sense of humor. Being a repeat 'customer' I feel that the overall quality of the treatment has remained consistently high."
"Dr Sieja reviewed my medical records, and after a thorough examination, he advised me to see a different GI with a unique skill set. He called the specialist and discussed my case with him. My visit with Dr. Sieja was positive and informative, he explained my medical issues in great detail and ways to correct it. I appreciated his honest opinion regarding my case."
"The pre-op communication was excellent. I knew what to do and what to expect. The process of checking in and getting prepped was fine. The procedure was as expected. Quick, painless and easy."
"Dr Trouillot explains everything very simply and listened to my concerns. I would recommend him. He helped me with my issues and I would go back if I needed any assistance."
"My procedure completed by Doctor Thomas Trouillot M.D. was outstanding! The doctor explained everything about the procedure that he was going to complete and asked if I had any questions prior to proceeding. The doctor also explained there was no time limit on completing the procedure, it depended on what was found. I can highly recommend Doctor Thomas Trouillot M.D.!"
"I am very grateful to Dr. Rufner and the staff for their high professionalism and excellent care. I felt like I was in good hands. Highly recommend. 👍👍👍"
"Dr Rufner was very professional and courteous. After the procedure, he talked to me about his findings and explained what it meant and when I should return."
"I get really good attention and am listened to. When I call with a question, I get a follow up call back. I had labs drown and Dr. Brenner called me herself to tell me that they were normal. Often times a normal result has not been call personally by the treating physician. It is here. I’m impressed and I’ve had IBS for over 30 years now. So, that’s saying a lot"
"Thanks to Dr Brenner my colonoscopy was amazing! The anesthesiologist was helpful and amazing also! I would recommend this office to anyone that has to have a colonoscopy. The entire staff was 10 Stars if that's a good rating... 20 stars is better! Thank you! G.Terry"

"Dr. Runner was very helpful in that he spent the time to discuss all my concerns and answer all my questions thoroughly. As a result, I have a much better understanding of my reflux issues and appropriate treatment. This was one of the best experiences I’ve had in a long time with a doctor."
"As always, the staff are wonderful and return calls promptly. Dr. Rufner listens to what you have to say and never makes you feel rushed. Unfortunately I have had to return many times because of my stomach issues but he always tries to figure out different ways to help me. I trust Dr. Rufner with my health and wouldn't go anywhere else."
"I felt I was well taken care of throughout the procedure. I didn't go with five stars because the procedure was delayed. This was a colonoscopy and as you know they're not very much fun. Other than that everything was fine."
"Dr. Rufner was thorough with his questions and exam. And he gave me some suggestions for the near future. He seemed genuinely interested and capable."
"Dr. Rufner is wonderful. Where do I start. First, he really knows his stuff. But I guess that’s a low bar for a specialist. More importantly, he took the time to explain everything to me in great detail and didn’t rush anything. Second, he is one of the most personable and relatable doctors I’ve seen In my longish life. I highly recommend him"
"This is a very clean and modern location. Everyone was very nice and patient. Dr. Brenner's bedside manners are excellent and appreciated very much. I felt comfortable and at ease. Thank you!!"
"Colorado Gastroenterology Aurora CO provided one of the best colonoscopies I’ve had. Staff is most caring and respectful. A very comfortable no-rush outpatient facility. The oral fluid home preparation is much improved (More tolerable, taste, Less time & volume, part-1 the night before, part-2 The morning of medical procedure). A+ experience!"
