Eamonn Elliott is to join Rockliffe Hall near Darlington as chief executive.
He will move from the Grand Jersey hotel, where he is credited with taking it from four- to five-star status and overseeing its restaurant's award of a Michelin star.
Elliott joins the hotel, which is celebrating its fifth anniversary next month, in December.
As well as working at the Grand Jersey hotel, Elliot spent eight years as general manager of the Devonshire Arms at Bolton Abbey in North Yorkshire.
He said: "I look forward to working with the Rockliffe Hall team and helping them take the resort into its next chapter. I want to make a statement of intent - I believe that the infrastructure, foundations and quality of Rockliffe Hall demand the best team in the country. I look forward to seeing the business embrace this challenge and establish itself as one of the top culinary, golfing, spa and hospitality destinations in the UK and Ireland."
Rockliffe Hall chairman Warwick Brindle added: "We already have outstanding people that have made us a great success in the last five years and this appointment strengthens our team as we go into the second phase of development at the resort."
Occupancy levels at the five-AA-star, 61-bedroom hotel have increased by 25% since its first year, going from 52% in 2010 to 78% for the period ending June 2014. It now has over 320 employees.
