About German Oliver, M.D.

Why did you choose to specialize in Gastroenterology?

It’s one of the fields that is very challenging because we work with multiple organ systems. Here, we deal with esophageal pathology, gastro pathology, liver pathology, pancreatic pathology—it’s among the most all-encompassing subspecialties of internal medicine. There is a lot of variety in the day to day work. I love talking to my patients, listening to them, getting to know them and helping them live the best quality of life possible.

Do you have a specialty of interest within GI?

Areas of interest include GERD and colon cancer screening.

Undergrad: The University of Puerto Rico (Magna Cum Laude) and Internship, Residency and Fellowship in Gastroenterology: Walter Reed Army Medical Center.

Preparing for a Colonoscopy is never a positive - is what it is! However. Dr. Oliver and ALL the staff made the actual procedure very easy. This os my second procedure with Dr. Oliver and strongly recommend him and the facility.

This was my first time going to Texas Gl and the care I received was At in my book. I am a registered nurse myself and I couldn't have had a better experience or a better patient outcome. The 2 ladies in the front office were very nice to me. Julie was my incoming RN and started my IV which was so quick and painless. She was so kind and made me feel so comfortable considering I was so nervous to get my first colonoscopy. Janice was also so kind and she assisted Dr. Oliver with the colonoscopy. The nurse anesthetist was great as well as the recovery nurse, Brandy. Dr. Oliver had a great bedside manner and made me feel at ease with the procedure. I was in and out in a timely manner. I appreciated the fact that someone called to check on me the next day to see how I was. It all went smoothly from the time I checked in to when I left. Thank you Texas Gl for being so awesome!!
