After almost half a decade in-house at Tenet Healthcare Corp., a Dallas lawyer is returning to Haynes and Boone to help lead its health care practice.

George “Bill” Morrison rejoined Haynes and Boone as a partner in Dallas, and as co-head of the  firm’s health care and life sciences practice group. He comes fresh off more than four years as assistant general counsel at Tenet, a Dallas-based hospital management company with facilities all over the country.
