Dunn joins Nat Geo-Lindblad as its first sales support executive from Fred Holidays where she served as relationship executive for the operator's river cruise brands.

Prior to her four years with Fred Holidays, she spent five years with Star Clippers as reservations manager and sales consultant, and had also held positions with Ama Waterways and Fred River Cruises.

In her new role, Dunn will provide general trade support including organising fam trips, providing content for agents, managing brochure requests and assisting with trade shows and events. She will also look after "lift and shift"-style social media posts and offers.

Dunn will report into Danielle Bates, Nat Geo-Lindblad's head of UK sales. Her appointment comes six weeks after the brand named Karen Hollands as its new expeditions sales and concierge specialist.

Bates said: "I'm confident her knowledge, skills and energy will help us to enhance service levels as we target major growth within the expedition cruise sector. Her appointments reflects both the momentum of the business as well as our commitment to supporting our trade partners.”
