"Treated very well !!"
"He’s a very good doctor and seems very nice. He explained everything."
"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!!"
