Dr. Tosiou was great, He listened to all of my concerns and addressed each of them with me. I felt that I had a complicated case. He put me at ease, he deals with those types of cases on a daily basis. I appreciated that he took the extra time with me to go over tests and procedures that he ordered.

Dr. Tosiou is a very thorough physician. He is also a truly nice man. I was so impressed with my first visit. Today he performed an Endoscopy and Colonoscopy which he explained in great detail. Northwestern is fortunate to have this Gastrointerologist and so am I.

Dr. Tosiou is a wonderful example of a Dr. who is professional, kind, concerned and very knowledgeable in his specialty. I feel extremely indebted to him and Northwestern should feel the same. Not many doctors like him out there anymore.
