Gemma Ashworth joins Riviera to take up the role, succeeding Amanda Docherty, after a short stint with Discover the World.
Ashworth was one of a handful of UK travel trade professionals who lost their jobs earlier this year when Carnival Cruise Line shuttered its UK office.
Riviera said it had seen year-on-year growth with home-based agents of nearly a third under Docherty's leadership, praising her efforts to build "a loyal and engaged community of agents".
The channel is currently the fastest-growing area of the escorted touring and river cruise specialist's business.
