"Clinical excellence + compassion and genuine caring wrapped up into one human being is the best way I can describe Dr. Thyssen. He is a skilled GI doc who listens, asks questions and works with you to make sure you are getting great care. I am a nurse and really picky about the doctors I choose for myself and my family - Dr. Thyssen is fabulous!"

"Had a colonoscopy today, never pleasant but Dr.Singh made me feel very comfortable. Would highly recommend Dr Singh and her facility (SIG) for any proceedures needed. Everyone there was great and makes you feel at ease from start to finish."

"Dr. Root, the techs, nurse anesthetists—everyone was so amazing! Really made me feel at ease and cared for throughout the whole experience. It was my first colonoscopy and I couldn’t have asked for a better team."

"Dr Root is fabulous. I had tried to have a colonoscopy the day before with another Dr who couldn’t perform it due to the difficulties with the prep prescribed. Dr Root got me in the next day, and while I was still having issues, he was able to do it, but it took him a bit longer. I so appreciate him staying with me to finish the procedure."
