Dr. Katilius is great. He did my last colonoscopy, and I wanted to make sure he did this one. I didn't want anyone else. Great doc. Listens, explains, talks. Really make a person at ease and confident in having the procedure done.

Dr. Was very well learned and shared good information. His bedside manner was not the greatest as during my examination he asked a question about If I ever self treated my issue in the past that assumed I was part of a lower socio economic class. That immediately made me uncomfortable but the procedure/surgery had already begun. The procedure ended well enough but that reference was not professional.

Concern was addressed with care and dignity. Explained with great detail both pros and cons of the procedure.
