"Dr Nguyen takes his time to listen to his patients and make sure that they get proper diagnosis. He has excellent best side manners. I was recommended by several family members who also see him. Also when I called his answering service after hours he had called me back within 15 to 20 min. It shows that he cares for his patients."

"My first time impression of Dr Nguyen is he is a very sweet Dr and has great bedside manner … He is the type you can feel comfortable with and he genuinely cares and is very knowledgeable in his field with digestive illnesses and disorders … I would definitely recommend him if you are looking for a Dr who cares about their patients , who is knowledgeable and who is a good listener instead of the type of Dr that makes you feel rushed or don’t have the time of day for you when you are trying to express your concerns about your health …"

"Being a Bariatric patient, it was important to me to find a Gastrologist who understood the “make-up” of my new stomach. I did a lot of research as those types of doctors are hard to find. Then, I found Dr. Dang Nguyen. He is very friendly, professional and thorough. Dr. Nguyen is patient with me, listens to my concerns about my body and answers all my questions without making me feel stupid. I recommend Dr. Dang Nguyen without hesitation."

"I have been a patient of Dr. Ngyuen’s since 2019 due a chronic GI disease. Dr. Ngyuen is personable, compassionate, and has an excellent standard of care. The office is always inviting, and his team is truly committed to serving patients under his care. I have had an emergency in the past and the team immediately made themselves available to assist. I want to thank Dr. Nguyen for not only being a great Physician, but just an overall wonderful person."

"Amazing doctor amazing care and amazing experience. I truly believe the only way we can stop the advantage being taken on the consumer’s by greedy establishments like doctors offices, lawyers and others is to share our personal experiences. Let the world know about the bad customer service. If you need a G I doctor please consider Dr. Dang Nguyen, e is Amazing"

"Meeting Dr. DANG NGUYEN was one of the best thing that happened to us here in Houston when we moved. He did my colonoscopy. His staff are very knowledgeable like him & with great customer service. Dr. DANG NGUYEN will see to it that all your concerns & questions will be answered & he takes time explaining everything about your procedure. Its more of taking care of you not all about money compared with the other Gastro that we met. I still have some stomach issue & visited him lately & again its a great service given to me. He is very consistent. Dr. DANG NGUYEN will be our official Gastroenterologist & was able to spread the good news about him to my neighbors, friends & family."

"I have seen Dr. Dang Nguyen only one time and have not been treated as of yet, however, I decided to go ahead and write this review because I am already impressed with the Doctor and staff. First of all, Dr. Nguyen LISTENS and this is very important to me as a patient as I have a total fear of doctors these days that only see one way and one way only. He was also confident, and that made me feel safe and secure in his hands. I hope that everything continues to be this way. I was also to have a procedure done, but could/did not do so because I was afraid of insurance issues and such, and I received a phone call from Natalia, one of the staff members at the office, and she was SOOOOO thorough and amazing in telling me and letting me know how it works with procedures and cost; NO OTHER MEDICAL STAFF WORKER IN HOUSTON EVER EXPLAINED it as she did where it was easy to understand....not even my own insurance provider that I am under! She is truly amazing! I really hope that all continues to go well with my experiences with Dr. Nguyen and his offices/staff."
