Patient Satisfaction Reviews

The CORE Institute is focused on providing an exceptional patient care experience. To ensure that we are holding ourselves to the highest standards, we measure all aspects of patient satisfaction with the National Research Corporation, an independent patient satisfaction company. This service partnership provides the technology to display ratings on our physician profile pages, and all ratings are verified and submitted by actual patients.

Responses are measured on a scale of 1 to 5, with 5 being the best score.  These reviews have been submitted by patients as a reflection of their views and opinions. The resulting ratings are not directly endorsed by and do not necessarily reflect the views of The CORE Institute.
