HLABHM was founded in 1976 and is the state's largest and oldest local chapter affiliate with over 250 current members. HLABHM's members are primarily administrators and managers of medical practices, clinics, large and small group practices, and freestanding, hospital affiliated and university affiliated medical groups. HLABHM typically meets nine times a year at The Club.

Its core purpose is to continually improve the performance of medical group practice professionals and the organizations they represent.
