The physicians are very nice and friendly, however Group Health associates billing Department has got to be the worst i have ever seen. From Billing errors, to flat out dishonesty. They changed my bill amount three times and after 4 months had past and countless phone and email conversations, with G.H.A. billing department denying any wrong doing the entire time, i was finally told that they were at fault all along, however there is nothing that they are willing to do about it! New patients beware!!!!
