Why does this provider not have a star rating?

Our goal is to provide our patients and visitors with correct and useful information. We only post provider satisfaction information from clinic surveys when they are returned from patients.

This provider has not had surveys returned that meet the necessary sample size

About Our Star Ratings and Comments:

Randomly selected patients are sent patient satisfaction surveys after their visits. We get thousands of survey responses each year. The responses are used to improve patient experience and recognize staff members for the care they provide. Patient survey responses are also used to make star ratings for each provider.

For the star ratings and comments, all feedback on the provider web page is posted as it was given from patients. Comments that do not apply, risk patient privacy, or are not appropriate are not posted. Star ratings and comments come from a number of survey questions. A star rating is not given if a provider only has a small number of survey responses.
