Newtown swooped to sign Cadwallader in the January 2015 transfer window from Cefn Druids. The tall centre-back returned to Latham Park for a second spell after a four season absence. In the 2017 summer, it was announced that Cadwallader would become a coach of Newtown and he registered as a player only in emergency.
Cefn Druids had re-signed defender Gavin Cadwallader for the 2014/15 season, after the tall centre-back was a prominent figure in the Druids' Championship winning season.
Born in Shrewsbury, he lists Aberystwyth Town, Airbus UK Broughton, Newtown and Shrewsbury Town as his former clubs.
