— Boston Consumers' Checkbook

"Doctor who discharged me was very rude and very irresponsible/ unprofessional. ... I explained the pain was still there... She told me she would prescribe pain medication... The nurse then came in and handed me the prescribed meds which did not have anything for the pain..."

— LocalityBiz user review

"I received terrific care in CHA’s emergency room (Cambridge Hospital). However, dealing with the billing department has been a total nightmare. The employees there, in marked distinction to the healtcare providers, are uncaring and completely incompetent."
