5.0 Review from R.J. Source: Google Oct 26 2021

"Dr. Thyssen was very personable and patient in answering my post-procedure questions, as were his support staff. The experience was calm, smooth and very professional. I cannot rate Dr. Thyssen and the Advanced Endoscopy Center too highly!"

"All those involved were very professional and made the experience a more bearable one, considering that a colonoscopy is not a fun experience. Dr. Thyssen is amazing!"
