Houston Regional Gastroenterology

My last visit was s consultation about a recent colonoscopy. All had gone well and he gave me some great news. He is always very thorough and helpful with questions. His staff is just like the doctor. Very professional. I would highly recommend Dr Dugan!

Dr. Dugan is so awesome! With excellent communication skills and patience, he took the time with me to explain my results from my last two colonoscopy procedures ( done by a retired doctor). It really helps to understand how everything works! I was able to ask questions and didn’t feel rushed! He’s the best!

Dr. Dugan has a great beside manner and welcoming demeanor! I felt very comfortable the moment he started talking to me. He explained everything in detail before and after my procedures. Going to the doctor is already daunting. When you feel your Doctor cares about you and your care that makes a world of difference. I felt very at ease with Dr. Dugan and his staff. I would highly refer to Dr. Dugan!

Dr. Dugan is very professional, experienced, and knowledgeable. He's also very personable with a great smile and caring manner. He's willing to talk you through your symptoms and come up with solutions together. Thank you, God, for Dr. Dugan.

I was a new patient with Dr. Barriento five years ago, and was very very impressed with him, and his staff. I am back again 5 year later for another scheduled colonoscopy and the office visit with him and the staff was more impressive and professional.
