Simon Mackenzie will be supported by Marie McNeela, who was recently promoted to Managing Director of Intertrust in Guernsey.
The firm say the pair’s joint working will “further strengthen the company’s position across the islands and provide superb client service”.
Mr Mackenzie said: “This initiative demonstrates how committed we are to the Channel Islands, our people and the clients that we service.
“With our Jersey and Guernsey teams working more closely together, we will be able to strengthen and expand our business across the region.”
