Andy Cowan, head of wealth advice, said: "We see this transition as a very exciting step for our business, and one which reflects Towry's commitment to place our clients at the heart of everything we do.
"In their new roles, Jon, Neil, Andy and Rob will be able to sharpen the focus of the service we deliver to clients; improve the quality of the advice we give; improve the degree to which clients are benefitting from all elements of our proposition and focus on the effort to attract new clients to the business."
