The former NHL goalie from Brantford, Ont., will move to North Carolina from his home in the Detroit region after signing the multiyear extension.
"Greg has been an integral part of our coaching staff for the past two seasons," said GM Jim Rutherford. "He has worked well in helping develop our organization's goaltenders and we look forward to having him in Carolina on a full-time basis."
Stefan, 45, began his coaching career in 1993 as an assistant with the Detroit Jr. Red Wings, who later became the Plymouth Whalers of the OHL. Stefan served as the team's assistant coach through 1998 and rejoined the Whalers in 2003 as assistant coach and director of player development.
Stefan played nine NHL seasons with Detroit after being selected by the Red Wings in the 1981 NHL entry draft. He compiled a career record of 115-127-30 with a 3.92 goals-against average for Detroit. He suffered a career-ending knee injury in a game against Edmonton on Nov. 25, 1989.
