Dr. Clemmons is amazing, he literally saved my life. I was misdiagnosed by 3 other GI doctors 5 times prior to seeing Dr. Clemmons. He preformed an Upper GI and Colonoscopy on me & has been the doctor to diagnose, manage & help me to achieve remission of Crohn's Disease for over 6 years now. His staff is very professional and personable. I tell any and everyone that I know to go to him if dealing with GI complications.

Dr Clemmons is very easy to talk to, an extremely trustworthy and capable dr, maybe one of the top Gastro docs in Houston. Problem is, I had an endoscopy without full general anesthesia and it was very uncomfortable. Then had Colonoscopy & seemed like I had very little anesthesia at all- I was writhing in pain, some of the worst pain I believe I ever experienced. Would put Dr C next to God if he would just use full General anesthesia. 2 stars cause his decision to use very weak anesthesia

Dr. Clemmons is a fantastic doctor. He is extremely knowledgable & takes the time necessary to explain any procedures, diagnosis & treatment so that his patient has a full understanding. I appreciate his patience & the fact that each patient is just that, a patient & not a number. I highly recommend Dr. Clemmons.

Dr. Clemmons staff worked to get me in on the same day I called for my first appointment because I was very ill. The staff was friendly and answered all my questions. Dr. Clemmons was kind and was quick to move forward with a treatment plan. Other physicians I had been to wanted to take the "let's wait and see what happens" treatment plan. Thank you Dr. Clemmons for taking care of me.

Dr. Clemmons was friendly, professional and a great communicator. Making an appointment for a colonoscopy was easy and his office staff were wonderful. He gave me all the information I needed and asked several times if I had any questions. His answers to the few questions I had were complete and easy to understand. He has a calm and polite manner that put me at ease. My appointment was at 8:00. I arrived at 7:40 and completed forms and I was taken back to an exam room almost right at 8:00.

Dr. Clemmons is an excellent specialist. He is extremely thorough, professional, and listens to what you have to say. This doctor does not have regular hours. He reviews your test results and call on weekends!! There is no waiting long periods of time to hear tests results. I have referred several to Dr. Clemmons. They are as happy with him as I.

Abrupt, spoke over me, would not allow me to describe my symptoms, prescribed medication which I could not take (due to other medical conditions and prescriptions), ushered me out the door without ever hearing me. I ended up in ER a few days later. I’m on a high-deductible plan too so I was paying out of pocket. What a waste of time and money and dangerous to boot. Staff is unprofessional and rude as well.

Dr. Clemmons has been my doctor since 1988. He always taken the time to explain everything concerning my health to me and has referred me to other doctors of whom I have always been pleased with. Thank you Dr. Clemmons for taking care of me and my family members. Respectfully yours, Elizabeth Teagle

Love this doctor. He was personable, professional, and knowledgeable. I moved to AZ, so his expertise will be missed.

I was not medicated properly prior to the colonoscopy. It was the most painful procedure that I have ever experienced in my life. I would never get another colonoscopy from this man.
