    Why No Ratings

    Currently, not all doctor ratings and comments are available. The number of rated physicians will increase over time. 
    The more ratings a provider receives, the more accurate and statistically reliable the data is. Providers with less than 30 ratings may not have patient ratings listed on their profiles.
