Patient Reviews
Sep 24, 2024
I looked up Dr Jelinek to recommend her to a friend and I saw some negative reviews and I had to respond. Dr Jelinek performed two colonoscopies within a three day span on me. (long story, don’t ask) Before that, she diagnosed my wife with a tumor that was successfully removed by a general surgeon. We both found her to be honest, straightforward and an excellent diagnostician and physician. She is a straight shooter and will not let you go down the path of an online diagnosis no matter how much you think it applies to you. We really appreciated her expertise and experience. We found her to be a great listener and her personality really meshed with ours. I think that she deserves a much higher rating than what is shown on this website,
