From just six founding EHR vendors when it was launched four years ago, the CommonWell Health Alliance now has more than 70 member companies whose expertise ranges far and wide.

"It continues to astound me how diverse and all-encompassing our membership is becoming," said Nick Knowlton, CommonWell's membership committee chair, as the alliance kicked off its Fall Summit and Annual Meeting.
