Patient Satisfaction Reviews

The CORE Institute is focused on providing an exceptional experience in every care interaction. All ratings are submitted by actual patients and verified by a leading company in the patient satisfaction industry. We measure all aspects of patient satisfaction. To ensure that we are holding ourselves to the highest standards, we partner with an independent patient satisfaction company. National Research Corporation provides the technology to display ratings and comments on our physician profile pages.

Responses are measured on a scales of 1 to 5 with 5 being the best score. The comments are submitted by patients and reflect their views and opinions. The comments are not endorsed by and do not necessarily reflect the views of The CORE Institute.
