Synchron director Don Trapnell said Smith's promotion reflected the enormous contribution he had made in developing the Synchron business in WA.
"Ken built Synchron's presence in Western Australia from the ground up and scores of Synchron advisers have benefited from his vast experience," Trapnell said.
"Western Australia represents around 10 per cent of the Australian population and yet 20 per cent of Synchron advisers operate there.
"This reflects the huge effort Ken has made building the business in his home state."
In announcing Nellini's appointment, Trapnell said he personified Synchron's NextGen advisers and was also the principal of Synchron member firm Lasan Financial Services Group.
"Albert is well qualified, technologically astute and runs an extremely successful business in Como, Western Australia," he said.
"He will be an excellent role model for the younger advisers we are currently mentoring into Synchron and is a valuable addition to our senior management team."
