150 words just is not enough for me to properly rave about how wonderful Dr Olsen is. I was very nervous about my visit but she was beyond fantastic, kind and very thorough. She took the time to go over everything with me and clearly explained everything. I would highly recommend her to anyone needing a Gastroenterologist. I won't ever go to anyone else!
