"Dr siegel is absolutely WONDERFUL. I have a rare vomiting disorder and he has taken care of me for almost 4 years. He has never let me leave a doctors appointment feeling unheard or not fully taken care of. He's even come in on his days off to take care of me when he couldn't fit me into his normal schedule.

Dr Siegel will go above and beyond to take care of you, listen, and treat you like a normal human being. 10/10 recommend to anyone!"

"Daniel Siegel is an excellent gastroenterologist and I would recommend him to anyone! Dr. Siegel approaches his patients’ unique circumstances methodically and thoughtfully, making sure to get to the root of the problem rather than applying a “quick fix.” He shows that he genuinely cares about his patients’ well-being, and I’ve come to trust his judgment tremendously. After years of symptoms and issues, I went to see Dr. Siegel and he was able to determine the root cause of my issues and identify a solution relatively quickly, and got me on the right path toward feeling better. A year and a half later, I’m significantly healthier and feel significantly better. I wish I would have gone in to see him sooner!"

"Dr Siegel is excellent and the staff was absolutely fantastic, special thanks to the anesthesiologist for the awesome nap."
"Simply the BEST! We’re “growing old together” as he promised when he diagnosed my UC years ago. Exceptional medical care with a very personal touch. I received a thank you note from the Rose Surgical Center after my recent colonoscopy signed by all 8 staff members involved in the procedure! Dr. Siegel’s expert care has been key to maintaining my active lifestyle for 20 years."
"Dr. Siegel is very conscientious, most caring and extremely knowledgeable. He always takes time (I have never felt rushed) and answers all questions in terms I can understand.

"Dr Siegal is absolutely my lifesaver guy!! Have been seeing him for almost 20 years. He is the reason I have had extra years. Thanks Dr. Siegel!! And thanks Michelle for always being able to make me feel so assured. You guys are the best of all!! Same as always!! He's awesome!!"
"Dr. Siegel has been a intricate part in changing my life forever! Four and a half years ago I was referred to him by my primary care doctor due the outcome of my annual blood test. The real conversations we had together in that first year were not easy but necessary. He kept me motivated to stay focused on my health and taught me to be patient. I feel like he was a coach guiding me through this experience. In my opinion lifestyle change is one of the more difficult things to do. No buddy likes change, but in the end you feel better for doing it. Well, I have to say I am healthier than I have been in 20 years and I owe so much of that to Dr Siegel. Thank you for all the support over the years Doctor!"
"Dr. Daniel Siegel saved my life by stopping 6, yes six bleeding ulcers During one emergency surgery! He has been closely watching me and stopping further serious problems by his constant vigilance. Dr. Siegel is at the top of his field he is also the top of his field preserving his patient lives with his skills, he does it with empathy and compassion. I’ve been fortunate to have him as my doctor is like saying the Atlantic Ocean is a little wet. Dr. Alex Goldsmith my concierge doctor and Dr Siegel work together seamlessly On my preservation and there are not enough words to explain their excellence in their field and communicating with their patients."
"This was my first time seeing Dr Seigel. I was impressed with his knowledge and attention to my situation and my needs. Personal touch of calling me himself that afternoon and discussing treatment plans was extra special. I appreciate that personal attention."
"I can honestly say that Dr. Siegel cares about his patients. He has gone above and beyond to get and resolve any GI issues I have encountered. He leaves no stones unturned. He is the best. Thank you Dr. Siegel for caring."
"Treated so very well. Much respect shown. And Dr. Siegel is absolutely the best. I waited till I got the right insurance back to see him again. His memory is fantastic."
"Dr Siegel has been treating me for over twenty years as needed. He is the really the best. He keeps up technically and always has good suggestions for all the various and often non specific internal ailments like IBS long before it was really recognized Amazingly caring with great bedside manners. Not enough space here to recite all his kindnesses e.g. hospitals visits when not my admitting doctor and even a house call."
"This dr has been the best specialist I have. He listens and understand his patients"
"Doctor Siegel is a very good doctor! He allows time for you to explain your health issue and he listens to what your saying.

Thank you Dr. Siegel and to Michelle!"
"I am 41 years old and was diagnosed with Crohn's Disease, Ulcerative Colitis and Psoriasis all at the age of 15 years old. My mother was amazing, she took me to Mayo Clinic, Cedars Sinai and found the best GI doctors she could. My mom was ahead of the curve, she did not believe nor listen to the GI doctor who said that diet was not that big of a deal and lifestyle, it was all about medication medication.. she got me a dietician, a nutritionist also a doctor who had Crohn's Disease himself which was amazing and such a help going through all of that at a young age... Well from 23 years old to 41 years old i controlled all of my diseases with my diet and my lifestyle, hospitalized many many times but i would never allow surgery on my stomach... i took Asacol like 30 pills daily then humira, remicade stelara and some others all of them before 25 and hated the side effects.. so all these years i have not found a GI that spoke about foods and diet and all of that until i met DR. SIEGEL.... wow when i met him i honestly felt like I finally have someone who studies and is up to speed on all the new treatments for my diseases. He is by far the best GI i have ever been to and also he is amazing with bed side talk and relating to the patient... We actually are trying some medication and i cannot believe no side effects and it has improved areas i did not believe was even possible anymore, i just accepted a certain level and was good with it.. Since seeing him i have seen more data and research on foods (thank god for my mother I have been eating this diet my whole life) and i really feel amazing and i am going to share all of this on my website so others know about lifestyle and foods that doctors never ever shared or believed in because they simply stopped learning and believed medication medication etc.... Thank you Dr. Siegel you really have improved and changed my life !"

"Dr. Siegel embodies the best in digestive health care. Regular appointments are just part of his overall plan of action. GI problems don't occur regularly and he has always made himself available when I've had a GI crisis. My GI health has been best since he's managed my cystic fibrosis related gut issues"
"This was not a usual Doctor visit: 1. My wait time was less than 5 minutes from check-in to being seen. 2. Dr Siegel personally came for me from the waiting room. 3. Dr. Siegel took me to his office where we discussed some health related issues and the upcoming procedure, not to a windowless room where I would sit and wait and wait. 4. Dr. Siegel escorted me to the exam room where he did a brief examination. The examination was not uncomfortable as they usually are for me because we had a detailed conversation in his office and I was prepared. 5. This appointment was by far the smoothest I've ever had for a Doctor visit. It was personalized by Dr Siegel from beginning to end."

He was willing to do whatever tests necessary in order to try and help me. He has also not given up on me despite me not being the easiest of cases. In addition, his medical assistant, Michelle, is also the friendliest and most helpful. I call her regularly and she is always ready and willing to help. I feel really lucky that I stumbled upon them. I would 100 % recommend Dr. Siegel."

"Dr. Siegel is not just the best gastroenterologist in Denver, but he is also one of the best doctors I’ve ever worked with. He is kind, compassionate, and empathetic, and his bedside manner is second to none. I spent years in decline without anyone to help me or believe me. I was hospitalized for five days and almost died but received no answers for several years after as other practices blamed stress, anxiety, or medications for my “mystery” illness. The first time I met Dr. Siegel, before I even spoke a word, he reassured me the symptoms I was experiencing simply don't happen to someone my age. He was the first doctor to acknowledge I was very sick. He said he was pleased to see me looking so well because that meant he had time to figure things out before something terrible happened to me. In the next breath, he promised me I was an enigma he would solve. And within a year of testing and treatment, he did. He diagnosed me with mast cell activation syndrome, a condition well outside the wheelhouse of many specialists. The fact he identified it as a Gastroenterologist is nearly unfathomable. Dr. Siegel subsequently referred me to an Immunologist who has helped solve the rest of my puzzle. Dr. Siegel kept his promise and gave me my life back. Now, Dr. Siegel works diligently with my PCP and Immunologist to keep me on track. Dr. Siegel continually works to educate himself and find new treatments to keep me intact as we hold out for science to catch up. Every time I go in, he reaffirms I can have a high quality of life despite a challenging set of circumstances. He reassures me medicine is advancing and the future will be brighter. His words of confidence and reassurance bring me hope and peace. I trust Dr. Siegel implicitly and recommend him to any patient who is suffering in the dark without a light."
"I was a stranger to Denver with a horrible gi bleed. He's an expert with your best interests at ❤"
"Without a doubt Dr Siegel is the best doctor I have ever seen. I first met him ten years ago when I had a complication from gall bladder surgery and was checked into Rose ER and he was the GI on call. I had a baby who was only two weeks old at the time and it was extremely stressful just having had a baby and also be sick and need to be admitted to the hospital. He was fantastic with me and my situation and he was able to get me admitted to a special section of the hospital that allowed me to have my newborn with me since I was breastfeeding. He then referred me to a new primary care physician and another specialist who have both turned out to be stellar. I have since had two colonoscopies and an endoscopy with Dr Siegel and the experiences have all been just a great as the first one. He also got my GERD under control and I get the pleasure of seeing him for occasional check ups for that. Dr. Siegel always spends time with me at any visit to make sure I understand what he is doing, what is happening to my body, etc. I know he has my best health as his priority. He still maintains high level of patient contact and care at a time where that is becoming less and less prevalent - he always walks out to get you from the waiting area, you are never seen by anybody else even to check your vitals. His assistant is also wonderful and efficient. I cannot say enough kind things about Dr. Siegel and his practice. I highly recommend!!"
