My husband has been having headaches since his neck fusion. Dr. Grudem took a ton of time to ask questions and do tests to not only address his headaches, but also several other health issues he was having. By far, one of the best doctors we have seen...very caring, listens, observes, offers many solutions...a great experience!

Dr. Grudem and all of his nursing and support staff I have worked with have been efficient, knowledgeable, and kind. They have repeatedly managed to provide me with treatments instantaneously that other clinics would take multiple visits and/or several weeks to arrange.

I accompanied my sister for her first visit with Dr. Grudem. He truly took the time to listen to our concerns, he asked questions to help my sister relax and better understand what may be going with her. Dr. Grudem was sincere and thoughtful in his actions and words. We certainly would highly recommend him to others needing a Neurologist.

Dr. Grudem and his assistants were prompt, efficient, knowledgeable, and caring. I had an emg which will lead to eventual surgery. Dr. Grudem and Janet were intent on making me comfortable and gave me all the options right up front. I was provided contact information if I wanted to confirm the next step. They left me feeling that I was in good hands. I was completely reassured and satisfied with this appointment.

Dr. Grudem was kind, intelligent, and patient. He took far more time than I have experienced to listen and ask questions. I loved that he thought to bring in a student (with my permission) who had just been studying what I was experiencing so she could get "hands-on" learning - what a great teaching opportunity! Janet was also extremely helpful and professional. Wonderful team!
