I had heard that his bedside manner was a little rough around the edges. I found him to have a dry sense of humor, took his role in my healthcare very seriously while chuckling at jokes and even making one or two. I was very comfortable with him.

Very good experience

Dr Gretz is not warm and fuzzy. but he was nice, polite and listened to me. even smiled at a 'joke' I made. His reputation as a gynecological oncologist is what i was there for.
