Philadelphia general manager Paul Holmgren made the announcement on Monday, as the Flyers welcomed back one of the most successful goaltenders in franchise history.
Hextall, 49, played 11 seasons for the Flyers, appearing in 489 regular-season games across three different stints with the team (1986-92, 1994-95, and 1998-99). He went 240-172-58 and posted a 2.91 goals-against average. His 45 playoff wins are the most in Flyers history.
Hextall spent the last seven seasons with the Los Angeles Kings as vice president and assistant general manager. The Kings won the Stanley Cup in 2012.
"Ron has a wealth of experience in the front office in various capacities," Holmgren said. "(He) will be a valuable addition to our staff."
Prior to joining the Kings, Hextall spent seven seasons with the Flyers in various roles, including pro scout. His first day with his new role will be Aug. 1.
As a rookie in 1986-87, Hextall went 37-21-6, and led the NHL in games (66) and minutes played (3,799). He was one of the league's best stickhandling goaltenders, and still holds the franchise record for most points by a goaltender in one season (8, 1988-89).
The Flyers went 23-22-3 last season, for 49 points, but failed to make the postseason.
