"Felt like they were actually listening to me. I've had stomach pain for years and was told that's just how it would be at previous doctors. She affirmed that it wasn't ok I felt that way and ordered tests done. Have to wait for next availability but the fact I have it scheduled has been stress reducing on its own. Great place 100% recommend if you are able to wait for an appointment."

"Dr. G and NP Medina are so wonderful. I have a super complicated stomach and immune disorder and they have always made me feel heard and understood. They helped me immediately and listened patiently- this is 100000 times better than the Houston Med Center where I initially started my illness journey. I would take these docs any day of the week. Fantastic team. Thank you."

"It did take awhile to get an appointment, once you see doctors and staff are awesome. They really take time to listen and answer your questions. I had cancer a few years ago so when I have any problems I worry. I feel a lot better after getting results and info from doctors"

"Starting yesterday, the person who called to confirm the appointment and collect payment was so kind. Then when I arrived for my procedures this morning, everyone at TDDC was friendly and caring and knowledgeable. I got signed in promptly by the friendliest person. I was moved into the prep room and was helped by Christie who was the best. Once I got into the OR, the nurse Monica was wonderful, the assistant David was fabulous, the anesthesiologist Mike was exceptional, and Dr. John was so supportive. This team knows how to alleviate a lot of fear and anxiety for patients, and I cannot say enough good things about my treatment today. I've been here before and it was a good place to be, but today, in spite of why I was there, was absolutely amazing! The facility was clean and efficient, and of course the medical staff made it an excellent experience. Thank you to all - and I hope I remembered the names correctly because they truly were special. If you have need a colonoscopy or endoscopy, have it done here."

I had an Endoscopy and a colonoscopy done by Dr. Kevin Dasher. He has always treated me with the utmost respect and is always willing to help. After I had finished with my procedure's, I asked him to recommend a primary care physician. He actually recommended 3 different doctors close to where I live. I would definitely go back to Texas Digestive Disease Consultants to get any tests or work that needed to be done."
