About Me

Doctor visits are too short and the time too valuable. We need to do a better job of communicating with our patients and making a human connection. Whether you see me for a screening colonoscopy or a complicated problem, I will try to make it a positive experience as we move together towards addressing your needs.

I had a colonoscopy done on April 18th, 2017. My nurse, Jean, was very nice! She wanted to make sure I was doing ok and answer any questions and listen to my concerns. She was very good at her job and quickly got me ready for my procedure. She was very friendly and I truly enjoyed talking with her.
I did have a concern about waking up during the procedure so the anesthesiologist (I can't remember her name) spoke with me. She more than adequately answered all of my questions and assured me that she would make sure I remained asleep until the procedure was over.
After meeting Dr Schiele in the procedure room, I briefly explained my previous and unpleasant colonoscopies and that I was concerned about being in pain. He said that he read my history and kindly reassured me that he would take good care of me during the procedure and do his best to make me comfortable. I felt that he truly meant what he said and that he took my concerns seriously.
As soon as I woke up, I immediately knew that this colonoscopy had gone better than the previous ones (because I hadn't woken up during the procedure). Dr Schiele met with my husband and I after the procedure to let us know how it went and answer any of our questions. I did have significant abdominal cramping and moments later was given medication to ease the pain; it worked great. My husband later commented on what a genuine person Dr Schiele was and I couldn't agree more.
Dr Schiele left a short time later and I recall hearing the staff say how much they enjoyed working with him. It is one thing to have your patients like you, but when the staff does too, that speaks volumes.
