I have been a patient of Dr. Gulinson on and off for many years. He is the most amazing Gastroenterologist. He listens to you and then starts his plan of action. I have had Crohn's disease for 30 years. Dr. Gulinson and his staff are very professional. I highly recommend Dr. Gulinson if you are having any gastrointestinal issues.

Careing and takes time explaining procedure

As a teacher, I like to get my doctor’s visits completed during the breaks. When a slot was not available, Dr. Gulinson overheard my conversation with his office staff, and opened up a slot for me. As this was the first time I have done any such procedure, I really appreciated the time and care taken to make sure I knew what to expect. When I had a question about prep, it was Dr. Gulinson who called me back. An overall very good experience from beginning to end.
