"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."

"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."

"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!"

"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 !"

"Yes we all get very tired of filling out survey forms. But in the case of Dr Siegel it is my privilege . This wonderful doctor and friend has treated me for many years through some major medical crises in my life. Seriously.

"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 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 have been seeing Dr Siegel for the past 2 years. He has continually shown that not only is he knowledgeable, but he is also kind and compassionate. My case has been slightly unusual/difficult and Dr. Siegel has never once questioned my suffering or invalidated any of symptoms. 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."

"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!!"
