The directors of Fleurets have announced that Willis, who joined the firm in 1984 as an associate, will depart at the end of September.
In his time at Fleurets, Willis has been a lead valuer on a number of major pub and hotel portfolio valuations, and acted as lead agent on a number of high-profile transactions and company sales.
Fleurets managing director Graeme Bunn said: “Martin has been a key part of Fleurets for more than three decades.
“The other directors and I have worked closely with him since we joined the firm and will miss his extensive knowledge and experience. We wish him a long and happy retirement.”
After joining Fleurets in 1984, Willis became a partner in 1987 before becoming a director when the firm incorporated in 1991.
He has served as the firm’s joint managing director, managing director and most recently as chairman in his 34 years with Fleurets, playing a central role in its national expansion.
