The 31-year-old ball-playing back rower has inked a three-year deal with the Perpignan club, and he is looking forward to plying his trade in Super League next season.
“I’m very excited about the opportunity to play in the Super League with a great club like Catalans Dragons,” said the former Manly player.
“I’m really looking forward to this new challenge and I hope to win some titles with the Dragons. The time is right for my family and me to experience something new in another country.
“It is a great place to live and I am looking forward to being part of the French lifestyle.”
Dragons head coach Laurent Frayssinous is pleased that a player who won the Clive Churchill Medal in 2011 has committed to his club.
“I’m delighted that Glenn has chosen to join us from next season,” said the Frenchman.
“We were looking for an experienced player to complete our pack for next season and it’s a great news for the club that we were able to attract a player of Glenn’s calibre. He will bring his qualities in attack and defence.
“He will also bring his experience at the very top level to the club along with his leadership skills. He is a true competitor who competes for victory every time he steps on the field.”
