CareSource was founded by Pamela Morris in 1989 in Dayton, Ohio with the goal of expanding health care for underserved populations. The plan was originally called the Dayton Area Health Plan (DAHP) which was incorporated by three hospital CEOs and located its first headquarters in the offices of the Dayton Hospital Association. Morris became the company's first CEO, and led the company until her retirement in 2018. DAHP began with a $500,000 grant from the state of Ohio to address a growing issue with the health care problems of low income citizens.
