“I would like to thank all the Titans staff and the club’s owners in the Frizelle and Kelly families, chair Dennis Watt and the board of directors as they have been extremely supportive of myself at a professional level and my family since we arrived.
“All of us are very excited to be staying with the Titans long-term.”
Speaking to the Herald last month, Titans head of culture Mal Meninga predicted Holbrook will be spoken about as one of the greats of the game by the time his career is over.
“Justin is a really good coach at the start of his career and, by the time he finishes, I believe he will be talked about as one of the better ones that has gone around in the NRL over history,” he said at the time.
Gold Coast CEO believes Holbrook is the man who will ensure success finally comes the way of the club.
“The positive influence and overall development of our squad under Justin’s guidance in his maiden year is very obvious,” Mitchell said.
“Justin is highly regarded by our player group and throughout the game.
“I am sure our members and fans will be thrilled that he will be heading up our coaching program for the next four years.”
