Halsey's arrival means Explore's trade team, led by agency sales manager Philippa Baines, has now doubled in size within a year ensuring the adventure specialist is better resourced to serve agents.
Besides Halsey, who will look after agents in the south, West Midlands and Wales, the team welcomed BDM Emma Bond in May, who has taken on Explore's northern and East Midlands brief.
Darren Phillips, meanwhile, joined the team in February in a newly created role designed to strengthen Explore's presence in Scotland and Northern Ireland, something Baines told TTG had "gone very well".
