Staff was nice but never got a return phone call when one was needed. My son had continuous abdominal pain after what we thought was the issue for the pains subsided,they ordered ct scans,upper endoscopy,nothing found and was told there were no more testing that could be done,and was just given a couple of diff prescriptions to TRY, we found a new Dr. That was able to help him. Granted we never actually saw the Dr. but was just a waste of time and my son's health suffered in the mean time.

I truly believe he is the best doctor I've seen in the past 20 years. He is always accessible, smart, to the point and very professional. Within three or four weeks, he and I solved a colitis issue that had me down almost 25 pounds over the past 5 years. I was very sick, frustrated and afraid. I trust him.

Excellent care and tender bedside manner. Takes his time to teach and provide patient education. Always demonstrates a pleasant affect and eases my fears. I would recommend Dr Rensch with confidence and enthusiasm.

If you want a Doc that brags on his credentials, how great he is and comes fully self absorbed with the biggest god complex even seen and heard... he's your man. Need for immediate care and decision making is non existent. Go to any other Doc than this guy!

Two of my family members have seen Dr. Rensch and I plan to also as well. He is interested in his patients (not just procedures) and has an excellent depth of knowledge, excellent in the procedures he does, and being a physician that refers to him, I have not seen any complications in my patients who have gone to him for procedures. The patients voice that he does a very good job communicating to them about their problem and explains things well including a follow up letter to them.

There's no question that Doctor Rensch knows exactly what's going on with you as a patient. He's been doing this for 20 years. He's trustworthy and highly recommended more than even this site can reflect. In reality being in the business as long as he has it's great that he still cares and that is genuine. His staff was caring and very helpful and the scheduling was also helpful to me they were able to get me in as soon as possible. I'm not sure you could ask for more.

Unprofessional and unintelligent
Sounds like you are a very unhappy person. Very difficult to believe that everything rates a one star for someone who is board certified in his field, one of 14 expert reviewers for the Texas Medical Board and the Eddy Palmer recipient for the one of the nation's best gastroenterologists. Please give me another opportunity, free of charge. Have a blessed day.

He seemed very knowledgeable, and I trust he knew what he was talking about but he is a personal space invader. He got right in my face when explaining my diagnosis and it made me very uncomfortable. His office staff wasn't overly friendly and unable to reach his billing office, always goes to voicemail, and I've left a few messages. I also had to wait over an hour to see him, but to his credit he was working me in with his current appointments due to my circumstances.
I would recommend him highly.
