Frank Aldridge is to step down as chief executive of Craigs Investment Partners after 16 years at the helm.
Aldridge said it was time to "pass the baton on to someone else" and take a break to do some mountain biking and spend time with family.
"Sixteen years as CEO, that is a long stint in anyone's term. It is time for a bit of a refresh."
Aldridge will continue to be an equity owner of the business, which is one of the country's largest private wealth managers. He has worked for the company for 24 years and became chief executive at the age of 31.
