"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!"

"The SIG team is the Best!!! I don't normally do reviews but I had too for this great group...I have worked in Healthcare for 20 years ( so I've seen it all) and I can say that Dr. Thyssen and his team went above and beyond my expectations! This was my first experience with Dr Thyssen, my appointment / procedure went seamlessly from beginning to the end, this group is on top of their game!!! They were prompt with scheduling, my procedure , check up and results. They also were able to provide pricing for the procedure(prior to it being done) which eased my mind. All of the staff were very kind too. It's very difficult to find a doctor, let alone, a team of knowledgable doctors who truly listen to their patients and have a great bedside manner. Thank You, to the SIG team & Dr Thyssen for a great experience! You guys are truly a diamond in the rough these days!!!"
