The Pittsburgh Penguins hired former San Jose Sharks and New York Rangers head coach David Quinn as an assistant coach on Wednesday.

Quinn, 57, joins assistants Mike Vellucci and Ty Hennes on head coach Mike Sullivan's staff. Quinn will oversee the team's defensive group.

"David Quinn brings a wealth of coaching and developmental experience across the highest levels of professional and international hockey," general manager Kyle Dubas said. "Quinn has a long track record of helping elite defensemen reach their full potential, and we look forward to the impact he can make on our defensive group and our entire program. Coach Quinn's experience, character, energy and enthusiasm make him a great fit for Coach Sullivan's coaching staff."

Quinn compiled a record of 137-185-50 as the head coach of the Rangers (2018-21) and Sharks (2022-24). Two of his defensemen, Adam Fox in 2020-21 and Erik Karlsson in 2022-23, captured the Norris Trophy as the NHL's best blueliner.

Quinn also served as the head coach at his alma mater Boston University from 2013-18. Quinn and Sullivan were teammates with the Terriers during the 1986-87 season.
