The organisation has created unique one-day and multi-week holiday packages for the islands which include pre-arranged airport transfers, hotel choices and dining and activity options.
Greg Phillip, former chief executive of the Nevis Tourism Authority, will lead the new team alongside his wife Moreen, who will manage the operations.
Phillip said he was "proud to have a team of such knowledgeable and experienced individuals" at Nevis Sun Tours.
"It is an excellent feeling to deliver travel industry innovation in service to travellers, travel advisors and other travel professionals," he added.
