Callum progressed through the youth ranks at Hibernian, finding his first taste of professional first team action in loan spells, firstly with Arbroath in 2009/10 and then with Brechin City in the early stages of 2010/11. Hibs manager of the time, Colin Calderwood, was sufficiently impressed with Callum’s performances that he rewarded him with a long term contract.
Callum didn’t have to wait too much longer for his full Hibs debut with his first game being a shock loss to Ayr United in the Scottish Cup in January 2011. He bagged his first goal for the club against Inverness CT in February 2011, a month in which he was award the SPL Young Player of the Month. Callum struggled to recapture his form the following season and soon found himself out of the squad.
In August 2012, Callum was sent on loan to Livingston for the season where he made 31 first team appearances, including playing every minute of the four Thistle v Livingston fixtures that season.
Callum spent the 2013/14 season out on loan as well, this time with Raith Rovers. He had a successful season as Raith won the Ramsden’s Cup, with the final being played at Callum’s home ground of Easter Road.
With Hibs being relegated to the Championship, Callum found himself back in the first team picture under new manager Alan Stubbs, making 12 appearances for the club before making the loan move to Thistle towards the end of January 2015.
After a slow start, not helped by a couple of niggling injuries, Callum made the left back slot his own with a string of impressive performances as Thistle cruised towards an 8th place finish in the league.
Callum penned a one year deal towards the end of the season which will keep him at Firhill until the end of the 2015/16 season.
Callum has maintained his consistent form in the opening months of the season and has been, arguably, Thistle’s best player in the opening quarter of the season.
