Excellent experience
Very professional.
I was very pleased with the doctor. He listened to what I had to say. I told him I think if we drank most of that prep liquid we would be better cleaned out. I was still having issues of needing the bathroom that morning.
Dr shiels and his staff did an excellent job. Thank you!!
Very good Doctor
Very welcoming Dr, I felt very comfortable and trusting with him doing my surgery.

Doctor Shiels, Was interested on learning to my condition. He was kind and offered a plan of action. I am looking forward to work with him. I am hopeful for my future.
My colon exam went well. I was never uncomfortable.
It was good to see Dr shiels miss the group at the ole Swedes. Knew his dad back in the day also. Excellent care as always.
