The Gypsies manager has agreed a new two-year deal at Dalymount Park and is hopeful of settling his squad ahead of the forthcoming season
Callaghan, 46, has been in charge at Dalymount Park since the beginning of the 2012 season and guided the club to a seventh place finish in the Airtricity Premier Division in his first campaign.
And with his initial 12-month deal finished, the club opted to offer the former Crewe Alexandra player a new deal. Callaghan's assistant, Owen Heary, has also signed a contract extension with the club.
"We have agreed a two-year contract extension which is good news as it will give the club and the squad stability," Callaghan told the Evening Herald.
"And once I have a budget in place I can start finalising deals for the players as I'd like to keep most of last season's squad intact," said the Bohemians boss.
