The financial services licensee has recruited former financial adviser Jason Gapps to the role of practice engagement and growth manager.
Gapps joins from Madison Financial Group, where he was the national practice manager.
Before that, he was a senior financial adviser at Sydney-based advisory firm Hunter Wealth Financial Advisers.
Earlier in his career, he held senior positions at ANZ Wealth, BT Financial Group, the Commonwealth Bank, Hillross Financial Services and OnePath.
Commenting on the appointment, Fortnum group chief executive Neil Younger said the firm was focused on working closely with advisers to build strong, thriving businesses.
"The needs and expectations of advisers and their clients are changing and we must also continuously evolve our proposition to support our aligned practices," he said.
"Jason is well-respected across the industry and a great addition to our team."
Starting next month, Gapps will report to Rob Skinner, Fortnum's head of practice engagement and growth.
"I've worked directly with many fantastic financial planning businesses and principals over many years, and I've been an adviser myself, so I have an intimate understanding of how advice businesses operate and the challenges and opportunities they are facing," Gapps said.
"Notwithstanding the challenges, this is a great time to be an adviser," he added.
"Advice is increasingly recognised as a profession, and demand is increasing, giving those who have decided to remain in the industry the opportunity to build exceptional businesses and help more people."
Gapps said he was excited about the unique role and the chance to work with Younger and Skinner again.
