"Dr Shults is a wonderful Doctor who truly cares about his patients and listens carefully. He goes above and beyond to make sure I was calm after waiting an hour to be seen. How embarrassing to be represent Chi Memorial in such a horrific way. There was only a few patients me included and Chelsea ignored me."

LocalityBiz review by Tessa Mustaffa

"I've generally had great experiences with any of the MDs at CHI Memorial... My biggest complaint is that they cannot seem to retain their amazing doctors... I do have concerns about my medical records. There've been times when the documentation doesn't *quite* match up to what was discussed in the office."
