Tony Iro, John Ackland and Craig Walker will all continue in their key roles working with new Vodafone Warriors head coach Brian McClennan next season.
Chief executive Wayne Scurrah confirmed Iro would remain as assistant NRL coach, Ackland as Junior Warriors coach and Walker as high performance manager.
"We're delighted they'll be with us again," he said.
"They have been critical contributors to the club's growth and success over the last few years and they'll all continue to have a vital role with us as we enter a new era with Brian McClennan as our new head coach next season.
"Tony, John and Brian all know each other well and have worked extensively together in the past while in Craig we have one of the best in his field in the NRL. He has made a huge difference in the conditioning, preparation and recovery of our players. It's an area where we have made significant progress each year.
McClennan said he was thrilled to have the trio on board.
"They're all quality men who are doing a fantastic job for the club," he said.
"I've had a lot to do with Tony and John over the years and we're all on the same wavelength. They're both coaches with a great feel for the game and they really understand and relate to players.
"Everyone can see the results of the job Craig is doing. He and his team have the players in terrific shape heading towards the finals. I'm really looking forward to working with him."
Craig Walker's career as a strength and conditioning specialist stretches back to the 1990s. He joined the Vodafone Warriors in late 2005 after a 12-year association with the Sydney Roosters. He has also worked with the New South Wales State of Origin side on numerous occasions.
McClennan officially joins the Warriors next month.
