"Over the past eight seasons, Paul has done an outstanding job," said Flyers owner Ed Snider. "He picked up the pieces of our disastrous season in 2006 and immediately made changes that took us to the Conference Finals the very next year, and we have consistently been in contention ever since. He's been a Flyer for 35 years and has earned the opportunity to run our entire organization.
"Ron is one of the league's bright young stars on the management side, and we're very fortunate to have him. He's had success in Los Angeles and will now put that experience to work for us as General Manager. We all remember the enthusiasm, work ethic and personality he had as a player, and we're excited to watch him bring those qualities to building a team that will contend for the Stanley Cup."
Hextall, who played 11 of his 13-year NHL career with the Flyers, was named Assistant GM and Director of Hockey Operations of the Flyers on July 15, 2013.
He returned to the organization after spending seven seasons as Vice President and Assistant GM with the Los Angeles Kings.
"I'm extremely excited about this new opportunity to manage the Philadelphia Flyers," Hextall said. "I look forward to working closely with Paul in our new hockey structure and working towards our ultimate goal of winning the Stanley Cup."
Prior to joining the Kings, Hextall spent the previous seven seasons in the Flyers front office. He became a pro scout in 1999 upon his retirement as a player, and served in that role for three seasons before being promoted to Director of Pro Player Personnel in 2002.
Holmgren was named interim GM of the Flyers on Oct. 22, 2006 before the team removed the 'interim' tag on Nov. 11, 2006.
